I am from the Isaak family and do have a Lydia Isaak. My Lydia was born in 1893 in Parkston, SD, but I bet there is a connection. My Isaaks go from Martin Isaak b. 1847 in Kulm, Bessarabia Russia Father Karl Isaak b. 1803 in Pabianitz, Poland
Lydia was the Granddaughter of my GGrandfather Martin's brother August Isaak.
