Hi Vanessa
Sorry we did not manage to find them either!
Can you tell us everything you know about the family, please?
Do you have certificates for the births and marriage? The addresses could be useful, as could the occupations of William and his father, if noted. Even the marriage witnesses might help pin them down!
Have you located any of the family in 1891 and Bridget in 1901, or do you know what became of her?
Hoping to help,
kind regards, Arranroots
