My 2nd great grandfather's name is Ludwick Chester Kusmierz he was born on July 15 1876 in wilkovas, rusnas, Poland and was married to Josefa Wojcik she was born March 17 1885 she was born in Poland from what I could find not sure of the town and they came to the U.S. from wilkotar (not sure spelling) russia in 1909 with their son Stanislaw born March 24 1908 and he was also born in wilkovas, rusnas, Poland. I'm planning a trip to visit Poland next year so If anyone has info it would be greatly appreciated.

As for the place name, I suspect Wilkovas and Wilkotar might be mispellings of the same name, perhaps Wilkołas (?) But that's just a guess.
