I have just begun to search. My mother-in-law is a Feldbusch. Her father was Roy J. Feldbusch (b.8/22/1899-d.1/9/1970)He was born in San Francisco; died in Redwood City, CA and is buried at Holy Cross Cemetery in Colma, CA. His father was Charles H.(Henry?) Feldbusch, and he was born in Germany - I'm not sure where. (b.2/8/1869 -d.10/27/1940). He had a sister Emma Gartland that I know of.(There may be others) He passed away in SF, and is buried at Mount Olivet Cemetery in Colma, CA. Their father was John D. Feldbusch, who was married to ______ Knapp. He was born in Germany. After he came to the US, he developed TB and decided to return to Germany. He stayed there for about 10 years. He decided to return because of the political situation in Germany prior to the war. That is all that I know about him. He is on the manifest for two ships at Ellis Island.
