Many thanks for your reply, Ruskie.
I did see a document noting that both Stoke-by-Nayland and Newton had workhouses (with not many residents) in 1776.
I was more curious about recording it in a marriage register. Maybe this was really, really common, but I just haven't come across it in my own family research so far!
