Hi George,
I'm looking at the same mystery from a different direction.
The 1930 census shows an Allister Verge and a George Verge living in Somerville with George Parks' family. They are listed as his grandchildren. Minnie is listed as daughter. There are documents showing them coming into this country with their mother "Annie."
George W Parks 57
Sarah E Parks 52
Henry G Parks 25
Margaret H Parks 17
Allister Verge 5
George H Verge 7
Minnie Parks 9
Percy Moore 25 (boarder)
