Barbara, I also have a Goucher relation in my family. David Casto has shared a large amount of information that was very helpful to me.
Washington M. Goucher was my 2nd G Grandfather. He married Emeline Tharp and they had a daughter, Mary, born in Coahoma County MS in 1830's. My family records show Washington and Emeline (Emma) lived the end of their lives in Houston, TX but I can't find any documentation that can be considered a primary resource.
Also, I can't be 100% certain that Washington really was the son of William Goucher even though it seems to fit with everything David shared.
Do you have any other records of this side of the Gouchers?
Thanks,
Dwayne Miller
