My grandfather, Julius Henry Schwandt was born in Markesan, Green Lake, Wisconsin on May 16, 1863. I am trying to find his father and where he came from. His father's name is Frederick Carl Schwandt. His mother's was Louisa Birkholz.
I have traced my grandmothers line back to Prussia in 1790.
Her name was Ida Henrietta Beyer (Beier).
