Yes, I do know of Clifford Moore and Donald Slator.
Clifford Moore was adopted to the Scott's Family, he was born as Clifford Allan Leonard Moore. Clifford Married Joane Delores Nichol who had five children, one of which is David (the one on this news feed).
The story I got from the Slator family was in 1929 shortly after the youngest was born (Ethel Lena June Moore) the mother Lenore Lena Foster died (maybe by a fire, unsure on the details) and the father John Albert gave up his children to local family friends, except for William and Keith who were taken to Indian Head to an orphanage.
I can try to help in anyway I can.
