As of this date, R' AM Teomim has no known living yDNA descendants listed in GENI, the most recent died in 1903. However, there could be descendants who are not listed on GENI. yDNA testing of one or more of these descendants would be a valuable addition to this family tree's knowledge base. If a person reading this is qualified to make the test and is willing to do so, please reply to this discussion.
Hi Adam — I am a Teomim descendant, but not through a Y-DNA line. However, I am slowly researching every branch of this family and trying to document any present-day descendants. In my branch, the surname was changed from Teomim to Zwillinger (its German equivalent), and I am following those lines as well. I will keep you posted on anything that emerges in my research.
