Hi Rosie and Mike,
Thanks for all you have researched. I'm trying to get my head around all the info, I know that there was a Jane Bowen born in Clun
BOWEN, JANE PERRY mmn
GRO Reference: 1864 M Quarter in CLUN UNION Volume 06A Page 592 I think that this is the one that married Bather.
I keep going back to the year of birth Jane entered in the workhouse 1863 and the connection to Churchstoke and her living in the Pentre, Churchstoke when Alice was baptised. I'm thinking she must have known the Trow family to trust them. But the only connection from a Bowen to Coxall is through Bather

I have been told that there are Coxall's in the Bishops Castle area (or were) which fits the area of your info but I don't know if she was born in Montgomery why she would say she was born in Lydbury Noth, maybe she wanted to start a fresh.

I do know that she worked at Maesmawr Farm, Caersws but unfortunately this information is between the census of 1881 & 1891 this may explain why she entered the Caersws Work house and not Fordon Workhouse which is in the area from which I think she was from.
Thanks again Joanne
