thank you so much Ciderdrinker for the speedy reply. I think I will have to look for Baptist burial grounds, as you say.
I think that is her baptism. I haven't gone beyond her marriage to James Williams, as she was his second wife and I'm descended from the first.
James was the son of David and Hannah Williams, baptised in 1822 at Bilson St Leonard's, though they were living in Highfield, Sedgley. I've been trying to track their deaths and burials but so far no luck.
Once again thank you.
