A possible connection with my Penrose family of Brittas and your Christopher Penrose.
A family tale passed down by my father mentions an adopted son (of his younger brother) of Richard Penrose of Ballykean and Brittas 1726-1756 being disowned for marrying a Catholic. The tale says he was called Daniel, but Daniel married Anne Doyle in 1800 and she was a Quaker without doubt and Daniel was not adopted. The tale said Richard had no children of his own, but he had 5 in the records.
However, Daniel had a younger brother called Thomas who married in 1793 and had Isabella and Maria and the name Sharp is mentioned, but am not sure if she is Thomas's wife. There is a lease between William Halpin and Thomas Penrose of Brittas in 1806, which could be the same Thomas, so maybe Thomas was disowned yet Thomas married after his father Richard Penrose died. The story may mean the Quaker Meeting disowned Thomas for marrying a Catholic lady, which could have happened. Maybe Christopher Penrose was a son of Thomas, although this is not shown and Catherine Doyle was a relation of Anne Doyle who married Daniel my forebear.
