The problem is that there doesn't seem to be a Cath Christian bapt in Andreas who fits age 85 in 1850. There's one bapt 1762, and another in 1772 (but she is daur of Richard Christian and Ellinor Teare, who married Ewan Garrett, so not her). Surely Cath wouldn't have said she was 65 in 1841 if b.1762? - That must be some kind of record, if so!
