Hey guys,
Yes that 1921 and 31 census seems interesting, odd that her maiden name is Crockett.
But him not being listed in the 21 census and then being on the 31 seems to go with the story that he was taken in as a young boy by his aunt and uncle.
Harry had 3 kids and there middle names were John, Lillian and William
So maybe that is the William he picked the middle name from?
