I'm looking for descendants of Oscar Richard Rosse. He was born in 1870 in Germany, immigrated to Texas circa 1886, and married Maria Christina Fischer in Colorado County, Texas and they settled in Kleberg County, Texas.
His son Charles William Rosse (married to Bertha Morgan) is my great-grandfather. They had only one child: Oscar David Rosse and I have the list of descendants from this marriage, which includes my mother.
I am looking for the descendants of Oscar Richard Rosse's other children.
Also, I have a family record that his parents (who never immigrated from Germany) were named Carl Lutwig Rosse and Frederika Schaller. I would love to know more about them.
