neither do I - no family relationships are given in 1841 - assuming that Cath's age is correctly given in 1851 then since ages are rounded downwards then John could be 20 thus Cath could be mother at age 40 - if john is 26 in 1851 then cath was mother at 44 - not that common but just possible - however Cath the widow is still in Derbyhaven age 80 in 1861 and I suspect is the the one buried Mal 18620411 age 87 which if so makes motherhood at age 50 - no.
