I am looking for information on Matthew Thomas Armstrong who was born in Ohio in 1845 and moved to Summit County, Colorado where he was a physician. He last appears on the 1900 US Federal Census in Colorado. He often went by M T Armstrong. He had a son, James Pooley Armstrong with his second wife Elizabeth Brown while in Colorado. He had three daughters, Maud, Pearl and Anna in Ohio with his first wife Sarah Victorine Carter. Thank you.
