On family search I have found a Robert Carr buried at Crosscannonby 11th oct 1834 and a Nancy Carr buried 28th aug 1836, possibilities?
Also on family search it lists baptisms of the children you listed plus a Sarah but the parents of some of them are Robert and Nancy and others are down as being children of Robert and Ann. Is Ann & Nancy the same person?
I also found a William Carr baptised 18th may 1834, only mother listed as Eleanor, and a Robert Carr was born with only mother listed as Sarah on 15th april 1832, both at Crosscannonby.
