About us

Lineage 01 status: this DNA matches various Treece, Dries, Trease, Treese, Trees, Treace and a few other testers thought to descend from Andreas Driess. We now have a number of Big-Y results for this lineage. A few likely branch signatures have been found from the extended STR markers that come out of Big-Y. The number of SNPs unique to each Big-Y tester tells us that the common ancestor is likely Andreas or at least close to his generation. The number of differing SNPs increases as the TMRCA increases, so we can use the differences as an age estimate and determine branching. We're still working on these results, and if anyone is inclined to upgrade to Big-Y, contact us to discuss.
There is a sale on this month. We hope some testers will upgrade. If you don't have a close relative who has tested at 111 markers, your upgrade would likely help us.
Lineage 02 status: most of the research for this line happens at the Pittman project. There are over eighty Big-Y testers, and as a result, there is a detailed genetic tree guiding the active genealogical research. Here is where you can find more.
We put up a link to the book "Four Generations of Andreas Driess with DNA Findings", Jef Treece and Mary Lou Treece Clegg, 2016. You can find it on the "Background" tab.
The name started as Dries, Driess, or Dreese and was anglicized to Treece, Treese etc.
Andreas, his wife Anna Maria Spengler, Cornelius, Peter, and John Adam Dries (all over the age of 14 years) immigrated from Germany to Philadelphia on the ship "Mary" arriving 29 September 1733. Also on the ship were Maria Barbara, age 13; Barbara Elisabeth, age 24 and Anna Maria Dries, age 11. Andreas is the ancestor of most of us.
Treece/Trease as a spelling is also known to be found in the UK. We have not at present identified lines who stem from such origins yet in this project, but they exist. We are always looking for testing candidates.
Some participants match other surnames, due to a NPE somewhere along the line. These are some of the most interesting puzzles to solve, and DNA testing opens the door to such puzzle solving.
