John:Silas Clarke Robb was my grandmother's grandfather.My grandmother's parents were Effie Viola Elaine ROBB & Gavin JAMIESON.They are both buried in Omaha, NE.
I am lucky enough to have a copy of Silas Clarke ROBB in his Civil War uniform. It used to hang in my grandmother's living room.In it, he has a huge bushy mustache, and dark brown eyes.He's buried in Arlington Natl cemetery with Hattie Stern, his 2nd wife.
Effie's Robb's mother was Mary Louisa McMahan--who divorced Silas in 1874 and ran off with a "furrier named Bullwinkle."Know anything about that story?
I have info on John McMAHAN, Mary L's father, who was wounded in the War of 1812 and later slain by Indians on his way home.My notes also state that he was one of the pioneer settlers of the Boardman, OH township.
All the other info that I have twins what you have posted, that the Robb/Raubs were originally from England and fled to Germany due to religious persecution.What I am having difficulty finding is any verification of "Catherine KRAUS", who married Jacob.Also, I too have Jacob Robb/Raub born in Hamburg, Germany, coming to the USA aboard the ship Nancy in September of 1751.
I am not so sure an Englishman would change his name from Henry George to Hans Jerg.
Almost forgot.I do have info on the PAINTER family, our John's wife---and Maria DUNLAP is actually Anna Marie Dunlap--sometimes called Mary DUNLAP.Nothing on the DUNCAN family, although my notes state that it is possilbe the Dunlaps, Duncans and Painters lived in German speaking communities, and may have been neighbors.I am trying to check that out.
My info may not be 100% correct, but so far the only errors are some of the spellings of the surnames.
