I know this is quite a while ago, but I am related to the Newenham's in Cork. A bit distant, but my 3rd GGM is a Newenham. I've studied this family for quite a while.
Thomas Newenham inherited Coolmore back in the 1700's. His Brother Edward (Sir) is my ancestor.
Edward would have inherited Coolmore, but he didn't want it, so he bought a wife for his aging brother Thomas, so she could bear children.
What pricked my ears up on this, is that I am also related to some Fitzgerald's (As my surname bears this name) in Cork too.
They were born in the City Centre of Cork back in the early 1800's (Market Lane and Dunbar St).
Do you know of the first names of these "Stonemasons"?
I have an ancestor - Fitzgerald, that was a Wheelwright, that came over to Australia.
