Hello Maycroft,
Would love to try to help but not understanding your request. It's a little late @ nite, so maybe I'm muddled.........
If Charles Groom (1770-1851) w/ wife Mary is the father of Benjamin and you have them born in Pulham St. Mary, wouldn't you be looking for Charles' parents likely born in England

What is the Utah connection??
This post was edited....maybe some clarifying information was removed

I see you posted on the Norfolk board and Mum44 responded but I didn't see any response to the information she found. There is also a "Cyndy" seeking what seems to be the same Charles Groom recently on the Norfolk board. Maybe you 2 should compare notes???
The IGI has a Charles Groom with dates/locale very close to yours but it is a member submission with no details so I would consider the lead very suspect.
