I looking for information about my g g grandparents. My g g grandfather James Clark was born in 1858 and died in Topeka, Kansas in 1921. He was married to Margaret Coulter. She was born in 1857 and died in 1941. I am not sure where they came from prior to moving to Topeka, Kansas. Their youngest child my g grandfather William (NMN) Clark was born in Topeka in1885. I am at a brick wall.
Any information you can provide, will be greatly appreciated.
