Barb-have you found any additional info on Thomas and Elizabeth Compo since your post? I have found both their obits in Watertown NY newspapers, but it did not list their parents names. Thomas came to the US about 1889 and Elizabeth came about 1893. In the 1900 US census they were living with their daughter Etta (Heneryetta} in Watertown,
NY with sons Charles and Robert. I have reason to believe that Elizabeth's maiden name was also Compo and her father was Isaac Compo from Athens, Ontario, Canada. Would like to hear from you.
