Hi Jacques, I am not sure as I have very little information on the Davids,my mother was a war baby and when WW11 ended her father John David went back to Ontario and that was the end of what I know. My mother was then given up but was raised by her grandparents on her mothers side. I know that John David had lots of brothers and his father's name was Wasif from Lebanon orginally. I think the parents had a store in Kingsville. Do you live anywhere near there where you could check civic records? I am in Victoria BC. John David's brothers that I know of are Gordon, Jake, Charlie, Bill, Fred and Freda a sister. I hope some of this sounds like it might fit you and if so I would love to hear back from you.
