My great grandparents on my mother's side were born outside Vilnius in present day Lithuania. Their original names were Mowscha Swirski and Zipa Byalou– changed to Morris Swyer and Celia White respectively when they immigrated in 1913 and 1908. Morris's parents were Peretz Swirski and Bailya Koganovich. Celia's were Shaina Pesha Alperovitsh (changed to Sadie Alpert upon immigration) and Aryeh Leib Byalou. Both had connections to the towns of Swir, Vileyka, and Vilna. Morris and Celia were married in 1915 and settled in upstate New York. If anybody's genealogy matches, or closely resembles what I have mentioned, I would be happy to hear from you!
