Maurice/Morris Abramson came from Poltava, Ukraine, according to familysearch.org. His son Leo Myron Abramson married Rose Welinsky (1897-1986) in 1926 in New Britain, CT. She was born in New Britain CT but her father Samuel/Shlomo Welinsky was born in Rusiskis, Lithuania. Familysearch.org has his ancestors going back many generations, naming the birthplaces in Lithuania.
If you go to www.familysearch.org, enter Rose Welinsky, United States, Connecticut, as search information, and you should find this information. This is submitted information (vs. extracted), so only as good as the submitter, who is one Ed Cohen who co-authored a book _Jewish Cemeteries of Hartford CT_.
You might want to also enter Leo M. Abramson in familysearch.org, as well as other names you are researching. Be sure and click on all links, such as "Pedigree" and "Family."
My interest in this family is Risa Maasel (born 1850 in Poltava, Ukraine, died 1921 Hartford CT), the mother-in-law of Morris Abramson. I just found out about her today and I believe she is a sister (or other close relative) of my maternal Maazel greatgrandfather.
