two distinct families - the one with Charlotte in 1851 is a large farmer John Christian + Mary Brew
the Cath in 1841 with Elizth is a very different family John Christian + elizth mcGlinn - she calaims birth in Douglas in 1851but I can't find a bapt unless a mis read to Hugh Glen (prob illeg) - they married in German - John is an ag lab.

the first Cath appaers to be Cath elizth (but I havn't an extracted bapt) - the second was bapt Elizth cath.
