Quick Update on AI “Reasoning” Models

Checking the Accuracy of Grandma's Age in the Census

Checking the Accuracy of Grandma's Age in the Census

by Steven Little


The AI-space has been ablaze with news about “reasoning” models since the release of DeepSeek’s reasoning model “R1” (which grabbed attention for its: 1) strength; 2) non-US origins; 3) open-source availability; and 4) cheap access). Now, as OpenAI releases their next reasoning models – “o3-mini” and “o3-mini-high” – it’s worth understanding what this “reasoning” buzz is all about...


Oversimplified, a “reasoning” model takes a few moments to refine its response before it gives you an answer...it’s as if the model, before providing its response, asks itself if it understands the intent of your prompt, thinks things through “step-by-step,” and reconsiders its response and revises it, all before responding to your prompt. You experience this “reasoning” during use when you see the chatbot taking from a few seconds to a few minutes before responding to your prompt–seriously, reasoning models do not excel at back-and-forth conversation.

Checking the Accuracy of Grandma's Age in the Census

Checking the Accuracy of Grandma's Age in the Census

Checking the Accuracy of Grandma's Age in the Census

by Gena Philibert-Ortega


Imagine you’re researching the U.S. census and you find your grandmother – but her age seems off. In each census she is listed as younger than she should be. She’s not 10 years older than the previous census, but may be only 5 or 8 years older. Or maybe she’s listed as older than she really is. What gives?


The usual answer I see posted on social media is that grandma was vain and wanted people to believe she was younger or older than she really was. That might be true, but let’s analyze that answer for a moment.

There are actually three ways you could answer the inconsistencies in grandma’s age listed on the census:


(1) She wanted people (like a new husband) to believe that she was a different age.

(2) She (and her family) didn’t really know how old she was.

(3) That’s not your grandma.

U.S. Citizenship and Immigration Services

U.S. Citizenship and Immigration Services (USCIS) is the successor agency to the Immigration and Naturalization Services (INS), which, along with its predecessors, dealt with immigration and naturalization for most of the twentieth century. In addition to providing immigration and citizenship services today, USCIS maintains millions of historic records on immigrants and citizens. A Genealogy Program was created in 2008 with the goal of helping researchers gain easier and quicker access to these records...

The USCIS Genealogy Program provides copies of files in response to Genealogy Record Requests submitted online or by mail (G-1041A). All file copies are from the five series of records listed below.

  1. Naturalization Certificate Files (C-Files), September 27, 1906 to March 31, 1956
  2. Alien Registration Forms (Form AR-2), August 1940 to March 1944 - As of May 17, 2024, all AR-2’s are available through NARA. 
  3. Visa Files, July 1, 1924 to March 31, 1944
  4. Registry Files, March 1929 to March 31, 1944
  5. A-Files, April 1, 1944 to May 1, 1951

Improve Your Genealogy Research Success

Understanding Double First Cousins in Genealogy

Learn how locality guides can significantly improve your genealogy research success.

by Todd, of Legacy Tree Genealogists


As we journey to discover our ancestors, we often find ourselves researching in unfamiliar places. It's tempting to jump right in and gather whatever information we can. However, this is not necessarily the most efficient way to start research in a new area, especially if it's an area where we will be conducting a lot of research. Creating a locality guide can keep us organized, save time, and uncover valuable resources we might not have otherwise known about. 

A locality guide is a comprehensive overview that contains information for researching a specific locale. Whether your focus is on a single county, state, or even a foreign country, a locality guide provides essential background information and directs you to the best resources for finding your ancestors. It is essentially a roadmap for your genealogical journey in a particular place. 

A well-constructed locality guide will typically contain: 

  • Historical background about the area 
  • Information about jurisdictions, boundary changes, and other local nuances 
  • A rundown of available records (both online and offline) 
  • Links to relevant online resources 
  • A directory of local repositories, archives, and libraries

Understanding Double First Cousins in Genealogy

Understanding Double First Cousins in Genealogy

Understanding Double First Cousins in Genealogy

by Nancy Ayres


The term “double first cousin” sounds like something out of a complicated family tree puzzle. But it’s real, and more common than you think. This unique relationship raises eyebrows and questions about everything from shared DNA to family gatherings.

Want to know if sharing grandparents with the same couple is as weird as it sounds? We’ve prepared everything you need to know about this fascinating familial bond...

Double first cousins share both sets of grandparents. Let’s say your mother had a sister and both of them married two brothers. Then, you and your aunt’s kid would be double first cousins.

...Double first cousins share a distinct genetic signature compared to regular first cousins. While regular first cousins inherit genes from two shared grandparents, double first cousins inherit DNA from all four. This difference is crucial for accurate interpretation...

Because there is one less set of grandparents in a double first cousin relationship, there is less information to find when taking your family tree back another generation. This allows for more in-depth research into known ancestral lines.

Using Published Genealogies and Local Histories

Understanding Double First Cousins in Genealogy

Understanding Double First Cousins in Genealogy

Following Footsteps: Using Published Genealogies and Local Histories  by Juliana Scuzs


Published family genealogies, biographies, and local histories have been at the heart of many a debate among family historians. To use or not to use, that is the question.  

Published family genealogies and histories are the product of research gathered by the author(s) and compiled into a book. Often, they focus on a particular set of forebears in a family and document lines of descent from them. Others may focus on the ancestry of famous figures, and some will also go back to the furthest documented ancestor and then back down the descendants of that ancestor, including many distant cousins of the subject.  

Local histories document the history of a location, typically a county or city/town, but sometimes also regions, states, valleys, etc. Biographical details on prominent residents and early settlers were often included. In the US, many of these publications were created around the time of the centennial as part of the celebrations. Notable connections to Revolutionary War heroes may feature prominently, while some relatives may have been omitted for various reasons... 

But the veracity of these secondary sources can be questionable. County and local histories are often referred to as “brag books,” because they were a chance for descendants to boast of their famous connections.

Genealogy Tip of the Day

The Town is NOT in the County


Varying civil jurisdictional levels can confuse the genealogist. One thing to remember is that a state or province may have different civil jurisdictions with the same name. In Illinois, the town Henderson is not in the county of Henderson. There are numerous other examples, particularly when smaller civil units, such as townships are considered. Always consider the possibility that someone may be confusing the town with the township or county of the same name.

Keokuk, Iowa, is not in Keokuk County, Iowa.

The list of examples is a very long one.

Genealogy Tip Of The Day

His, Hers, Ours, and the Neighbors?


When encountering a family of parent(s) and children, always consider the possibility that the children are not full biological siblings. Some children could have been from previous relationships either parent had and others could be theirs together. Even if there were no divorces or separations, previous spouses could have either abandoned their family or died. Left with children to support, remarriage was relatively common especially if the remaining parent’s economic status made it necessary.

There’s always the possibility as well that some of those “children” were children of relatives of one of the parents or a children of a neighbor that they took in. Household membership may be more fluid than you think–especially if there was room and child was old enough to help out with chores, farm work, or similar tasks.

Never assume that what appears to be a “husband wife and their children” actually is. It may not be.

Genealogy Tip Of The Day

Was It Really the First?


If a relative appears to have gotten married for the first time at a slightly older than normal age, look again. That first marriage might not have been the actual first marriage.

For a female, this means that what you think is a maiden name may not really be a maiden name at all but could be the last name of a previous husband. Not all marriage records ask how many times the bride and groom have been married before and not all records use a “Miss” or “Mrs.” before the bride’s name. And since men’s last names don’t change upon marriage, it is even easier for a man to have a first marriage that’s unknown to the genealogist.

Family stories about these marriages do not often get passed down to the current generation, especially if there were no children for the marriage or the marriage had a confrontational ending.

Genealogy Tip Of The Day

Easy Pickings


When I’m stuck on a family, I ask myself: am I sure I have found all the easy ones? Sometimes I have and then the work is more difficult. But other times there are easier members of the family to find and sometimes finding those individuals can provide me with additional information to help find the others.

These “easy pickings” include:

  • Individuals whose name is less likely to be spelled wrong in a census.
  • Children in a census whose ages are less likely to be off .
  • A relative who was better set financially and left more records.
  • A relative who received a military pension.
  • A relative who was in a different social class and left better records.
  • A relative who lived longer when perhaps better records were kept.
  • A relative who lived in an area that kept better records.

These approaches won’t always work. No approach always works. But it’s always good to ask if there’s a close relative to your “problem person” who might have left better records.
