Good evening. My name is Edward H. Holton. I live in Douglas, AZ. Alexander M. Holton was my great great grandfather. I am doing the Holton family geniology and have also run into a blank wall on the Holton side of the family after Alexander Holton. As near as I can tell, his wife was Clarissa Bartlet Denham and the Holton Family line takes off like a rocket from there.
