An update on the mitotree

 

FTDNA.

Back in September 2025, cousin Catherine received her initial mtDNA result and a place on the mitotree. This gave us a haplogroup for our shared maternal line ancestor Maria Jesus Vasquez. At the time, FTDNA's results showed a most recent common ancestor for this line was 850 BCE. The haplogroup recently updated, and now shows a most recent common maternal line ancestor dating to around 600 CE. 

The haplogroup should update again once the mtDNA kit for our cousin Joe is processed. He is also a descendant of Maria Jesus Vasquez from her daughter Maria Jesus Campuzano.

According to the discover report, this haplogroup migrated from the Athabaskan-speaking lands of Pacific Northwest Canada into northern Mexico.

Here's another image to celebrate Year of the Horse for Lunar New Year. This was taken on a street art walk in Downtown LA back in 2016.

Life in Saxony, 1817

 

Magdeburg, 1795-1800.

When Dorothea Sophia Gagelmann lived in the Province of Saxony, she was living in a region still finding its footing after a period of upheaval. The province had been created in 1816, cobbled together from territories ceded following the Congress of Vienna and conclusion of the Napoleonic Wars. The map of Europe had been redrawn, and families like Dorothea's were learning to navigate a new political reality under Prussian rule.

The province stretched across central Germany with its capital at Magdeburg, south of the towns of Gardelegen and the village of Roxförde where Dorothea Sophia appears in records. The region was among Prussia's most fertile, particularly the rich soils of the Magdeburger Börde near the base of the Harz Mountains and the valleys of the Saale and Unstrut rivers. Dorothea's family would have witnessed golden waves of wheat and rye rippling across the landscape, crops that made this province the breadbasket of Prussia.

Sugar beet cultivation was beginning to transform the countryside, grown especially in districts north of the Harz mountains and along the Saale. Market gardens flourished in towns around Magdeburg. Yet alongside this prosperity, sandy plains in the Altmark to the north yielded only meager harvests, reminding farmers that the land's bounty was unevenly distributed.

In 1817, most families still centered their lives around the village. These functioned as corporate bodies where peasant leaders supervised the fields, ditches, and grazing rights, maintained public order and morals, and supported village courts that handled minor offenses. Within families, the patriarch made all decisions and worked to arrange advantageous marriages for his children.

Yet change was in the air. The old feudal bonds were beginning to loosen. Agricultural reforms launched after the Napoleonic Wars aimed to free peasants from feudal obligations and allow them to become landowners. While reforms had some success - Prussia's cultivated land would expand significantly in the following decades - many minor peasants lost their means of subsistence and became agricultural workers.

The Napoleonic Wars had ended just two years earlier, and their effects still echoed through daily life. At the Battle of Leipzig in October 1813, the greater part of Saxon troops had deserted to allied forces when Napoleon was defeated. Families had lived through occupation, shifting loyalties. Prussia's economy remained under stress from funding occupation forces and war indemnities.

Much of village communal life centered around church services and holy days. The majority of residents were Protestant, following church traditions that would be formalized into the Prussian Union. The region is noted as having the highest density of churches in Germany today.

At this time, Prussia still had complex and inefficient customs laws, with different tariffs on goods passing between western territories and the Prussian heartland. Trade moved along the Elbe River and the network of roads connecting outlying regions to the center. 

Dorothea's ancestors in this region of Saxony lived in a place poised between the medieval past and the industrial future. They likely farmed fertile fields using methods her grandparents would have recognized, worshipped in village churches, and raised their families under the watchful eyes of both tradition and an expanding Prussian state. The railways, factories, and rapid changes that would transform Germany in the coming decades were still just over the horizon. For now, the rhythm of life followed the seasons, the church calendar, and the ancient patterns of village agriculture that had sustained generations before them.

Big Y Matches

 

Source: FTDNA. 14 Feb 2026.

The match time tree for cousin Greg's Big Y results shows two matches in the same haplogroup, with a most recent common ancestor born about 1234 CE. The time predictor tool on one match shows a range of 950-1650 CE, likely about 1350. There are also a few Y-37 matches that show a most recent common ancestor at about 1500 to 1550.

I provided a prompt to Claude that we have a Big Y match with STR differences 3 of 590, and what tools could I use to understand if this was an actionable match. The response was "A STR difference of 3 of 590 is actually quite close and could definitely be worth exploring. Here are several tools and approaches you can use to determine if this is an actionable match." I've already looked into the suggestions for using FTDNA's tools on the Block Tree, Match Time Tree and Time Predictor, so I'll skip down to Claude's suggestions on why this could be an actionable match.

"With a 3 of 590 STR difference, this suggests a recent shared ancestor, likely within the past few hundred to perhaps 1,000 years." This is consistent with FTDNA's statistics in the time predictor, and in the image above.

Next, Claude says "check for shared SNPs - do you share any terminal SNPs beyond your haplogroup assignment". This is good and gives me something to check.

"Compare family trees - look for surname matches, geographic overlaps, or common ancestral locations." So far, the surnames do not overlap, but from a geographic location we're dealing with northern Mexico and Spain as common locations.

"Review genetic distance - FTDNA should show a genetic distance value that helps estimate generations to a common ancestor." Also a good suggestion.

Claude recommends the following next steps:

  1. Contact the match 
  2. Check geographic origins - do the paternal lines come from similar regions? (I'd like to see a bit more information on common regions in Spain).
  3. Look at surnames - any surname matches in my own ancestry? (Not yet).
  4. Consider STR marker patterns - which specific markers differ? Some mutate faster than others.
I am rewatching the YDNA course on YourDNAGuide, and need to review the modules on STR markers.
