I posted the following question on Lithuanian Global Genealogical Society on Facebook:
“If anyone has information on Abromaitis, Bubelis, Kavaliauskaitė, Kalčinskaitė, Vaskaitė, please contact me.”
I was contacted by a man with the last name Waskelis.
“I have a Vaškevičius DNA match that comes from Simnas area. I’m wondering if Vaškevičius may be related to Vaskaite?” He also had Bubelis matches.
I compared his kits to mine and my brothers on gedmatch. No matches.
Then I checked Family Tree DNA.
No match for me to his names.
Then I found it: his great aunt and my brother matched.
Sure enough, I went back to gedmatch to find his aunt, and again, she matched my brother but not me.
Not a new lesson, but an important one: test multiple family members, and use multiple matching sources: Ancestry.com, Family Tree DNA, and gedmatch.
