Good question…
No easy to track down people with few clues.
William Melanson Junior was born in Yarmouth, Nova Scotia around 1906.
I was lucky to find him, but I know how to get lucky using the Mormons’ site.
No image is available of the marriage certificate of William Melanson, son of William H Melanson and Clara Douett (sic), born in Yarneaut (sic), N.S., Canada.
No doubt about it, he’s our man.
William Melanson, son of William H Melanson and Clara Doucet, born in Yarmouth, Nova Scotia, Canada, married Vera Anita Hiatt on October, 28, 1924 in Council Bluffs, Pottawattamie, in Iowa, U.S.A.
Now, what has become of his father of whom we lose track around 1911?
Another good question.

Beats me Pierre, I am lost now just like William Sr but I am still trying to find some new information on my end here.
If William Jr went there I wonder if his younger sister Gladys did as well since we have no trail for her.
