Thanks for your trouble, Mari. At present I've no idea what the link with Staffordshire was, nor how it came about. I've not found any other family there, prior to this. I was hoping that someone might have the church records, so that I can follow up any leads to see if I can make definite links. The Staffordshire website will certainly help, I presume, with Elizabeth's family, once I'm sure she's not a red herring!
Thanks again for your help. Good luck with your own research.
Regards, Val.
