Myrtle Viola Jones is my 2ggrandmother. Her mother's maiden name was Gertrude Daub. Gertrude was first married to Joseph Hoffert in Berlin (Kitchener), Ontario, who died. She then married William Jones (in Michigan, I believe)and had Myrtle, Hattie, and 3 sons who died of Diptheria.
I have also heard the name as VanDaub and that we are supposed to be of Danish decent, but have not been able to locate anything to support that. The Daubs came from Germany.
I noticed that you also had a posting for Christ Hansen and Amelia Rutzen. I am descended from them as well (through George and Hazel). Amelia has been a dead end for me as well.
We should have a lot of info to share if you are interested.
Myrtle's later marriages have me quite confused. I know she first married William Boone, ans was married to Walter Hill when she died, but in between, I have William Gee, Ben Roberts, and Willam Hooper/Hasper.
