The only info I have is from Golda Soffe's book - Rideouts in America. It does have lots of errors but is still a gold mine. It traces James' line back to the first Rideout to go to the US. It lists a son, John E., instead of James E. and gives further info on Harriet but not the others. Do you want any of this? The book is probably available to you at an LDS Library.
