Hi, Donna!
Well, if that were my Jane, it would certainly explain the previously puzzling fact of the marriage having taken place in Arbory. I'll bet she's the one. And Henry C is a child I never knew about...
The fact that Jane's mother had to go to Castletown to live with her brother explains what she was doing there. I think it's a viable possibility - I'm going to tentatively run with it.
Thanks!
Barbara
