Hi Wendy,
Thank you very much for your very kind reply, I have checked the three marriages you gave me but none seem to match up along with four other matches in the Birmingham & Yorkshire areas with no luck I will have to assume that she died a widow. I had already found the birth of her daughter Jennifer but no other information about her. I will have to keep on searching.
My very best wishes.
Fred Wheatcroft.
