"Booth" Was Not John Wilkes Real Last Name?

[Steve]

I couldn't find any family for John Booth, the silversmith who married Elizabeth Wilkes to see if I could independently trace his ancestry. His burial record didn't even have an age that I could've used as a clue. The only hint that I could find is that an Elizabeth Booth married a Thomas Goodchild at Mayfair Chapel (also called St. George's) on Feb 15, 1747. The same day John married Elizabeth Wilkes.

Has anybody ever heard of the Goodchilds or have heard of a Goodchild family associated with the Booth family in any way?
