More observations on Gedminer

 

Gedminer. 17 June 2026.

Earlier in the week I wrote about testing out the new tool Gedminer. When I first ran the tool using the GEDCOM I downloaded from Ancestry, I had 11,462 people in my tree (this includes groups of people from floating trees that I have built off my main tree to identify DNA matches). I followed some of the suggestions to fix errors, and am now down to 10,826 people after pruning some additional branches.

My tree consistency score has improved from 99.4 to 99.58% and the sourcing score has improved from 74.24 to 75.29%. 

I began building out my tree on Ancestry in 2005, and over the years a lot of questionable additions to the tree have stacked up. Gedminer is really useful to identify these errors, people without data, or branches that don't belong.

A Canadian Connection

 

Ancestry. Maine Marriages. 14 Nov 1898.

While looking at the tree for Canadian DNA match DG, I see Mary O'Brien of St. John's, Newfoundland. She married Garrett Coady in Torbay, Newfoundland in 1859. I emailed the Provincial Archives in St. John's (therooms.ca), and received a reply that a true copy shows the marriage as between "Garret Cody and Mary Brine" as written by the priest in the ledger at the Holy Trinity Parish in Torbay.

Garrett and Mary had at least the following children:

• Mary Coady, 1859
• William Coady, 1861
• Timothy Coady, 1871
• James Joseph Coady, 1874
• Bridget Coady, 1877
• Mary Coady, 1879
• Denis Coady, 1882

The record above comes from the marriage entry for their son Timothy Coady, in Penobscot, Maine. It's interesting to see Garrett listed as a sailor. I am still looking for other records for Mary O'Brien in Torbay, potentially for her parents so that I can see if she connects into my own O'Brien line in Newfoundland or if these records point back to Ireland.

Another source for information is in the Mannion Collection for Irish Migration and Settlement in Newfoundland. This is a next step.

Overlapping centimorgans

 

DNAPainter. Chromosome 12 for KDJ.

Last October I dove down the rabbit hole on the story of Mary Frances O'Brien, who worked as a governess for the child of Alberto Yoacham, Minister of Chile to Mexico in 1918. At the time I wasn't sure how this ancestor of DNA match JJ O'Brien might connect, if at all, to our O'Brien line. After spending some time on chromosome mapping using the tools at DNAPainter, I decided to look again at the segments in common with other known O'Brien DNA matches. JJ's segment, the dark green piece at the bottom of my Dad's chromosome 12, overlaps with another dark green segment belonging to a verified O'Brien match.

JJ's segment is small, 10.3 cM, but the segment is entirely within a 20 cM segment from EM, who is a descendant of James O'Brien from the Pennsylvania O'Brien branch.

Another potential O'Brien DNA match to my Dad, DG, shares 38.8 cM. This match is on MyHeritage and comes from Canada. When I map the segments in common, she has a 12.2 cM segment (dark green, at bottom) that overlaps with a longer segment in common with Mike O'Brien on chromosome 11. Interestingly EM also has a segment overlapping with Mike on this same chromosome (dark green directly below Mike's lighter green). DG has a smaller 8 cM piece on chromosome 17.

DNAPainter. Chromosome 11 for KDJ.

Now I need to look closer at DG's Canadian ancestor and see if it's possible to directly link her to my O'Brien line.

Testing Gedminer

 

Gedminer. June 2026.

On Jarrett Ross' Friday YouTube livestream, he demonstrated a new tool called Gedminer. It is browser-based, and currently free to use (although you can donate to the developer to support the project). Gedminer works with a GEDCOM (a structured file for storing family tree data) and provides a detailed analysis with suggestions for further exploration. Some screenshots below capture what Gedminer can do.

You can download a copy of your GEDCOM from Ancestry or MyHeritage, and upload it to Gedminer. The process was fairly easy, although it did take me a little bit of time to find the right place to generate the GEDCOM file on Ancestry.

Under the heading "Discovery", Gedminer has tabs for deep dives into your GEDCOM data, including Migration Analysis, a Census Toolbox, Gap Detector, Incomplete Families, a DNA Planner, and Plan Generator. The Migration Analysis is very cool.

The Plan Generator analyzes the GEDCOM and suggests highest impact research tasks.

I am going to try some tree cleanup on Ancestry and fixing of suggested errors, and then reload the updated GEDCOM. Gedminer can show progress improvements and recalculate scores. This looks like a very powerful tool.

Beckoning Cat

 

Photo by Patrick Jones. Madrid, 12 June 2026.

Walking around in the Mercado Anton Martín on Friday in Madrid, a square image of a beckoning cat next to the kitchen of Asian Army restaurant caught my eye. The swirling red script caused me to give the place a closer look. I thought it might be Khmer script, which I recognized from visiting Angkor Wat in 2016. I snapped a photo for later, and enjoyed some delicious dinner.

Upon my return home, I uploaded the image to Google Gemini and asked a simple prompt, "what language and script is in this image, and what does it say." According to Gemini, this is a modern yantra, "a type of sacred talisman in Thai spiritual culture...featuring a stylized beckoning cat wearing traditional Thai royal attire. Shopkeepers and business owners in Thailand place talisman papers like this at their storefronts or registers to magnetically attract customers, boost sales and invite good fortune into the establishment."

The text is written in a variant of the Khmer script (Khom Thai) historically used in Thailand for religious, magical or sacred texts. The language is Pali (Phasa Bali in Khom script), the traditional language of Theravada Buddhism. This is a Buddhist mantra for good luck, attracting loving kindness, customers, and popularity (paraphrasing).

The image got my attention, and I stuck around for Singapore-style chicken rice. Very tasty.

I also recommend Cutzamala, around the corner from Asian Army on the same level of the mercado. I ate there before the Mexico-South Africa game on Thursday night.
