I am also looking for my Ruoff ancestors. I have a Amelia Ruoff in my family tree. Unfortuantely, I have been unable to find who her parents and siblings are, or other information about her beyond what I have here:
Amelia Ruoff born November 6, 1858 at Wasseralfingen, Wurtemburg, Germany. Somehow she met a man named Emil Kettler, Sr. Emil Kettler Sr. was born December 24, 1847 at Oldenburg, Germany.
Amelia Ruoff and Emil Kettler, Sr. married March 4, 1881 in Los Angles County, California. They had nine children. Amelia died July 29, 1935.Someone in the family mentioned once that there were Ruoff cousins as the children of Emil and Amelia Ruoff Kettler called them their cousins. When I asked for more details about them no one in the family was able to provide any further details or information.
I am hoping that you might be able to provide some suggestions for how to find more information about Amelia Ruoff if there is no mention of her in your immediate tree and her parents and if or who her siblings might be. Looking forward to hearing from you soon.
