My Mother was Helena Mary Clemo, daughter of Frederick James Clemo. There is quite a enclave of Clemos in the Cornwall area of England. Look in the IGI with the Mormon Church. www.familysearch.org. This may give you some leads. I just pulled up every conceiveable name I could think of with the surname Clemo. Tedious, but you would be surprised once you start puzzeling together probable families. Clemo's were very clandish and pretty much stayed in one general area I found. Give it a shot. Good Luck
