Welsh Surnames in 1700-1800

[Gadget]

I have heard that daughters would use their mother's maiden name once their father had died. For example when giving their maiden name on a birth certificate.

Could you possibly give a source/location for this please, DMJ?

I've not come across it in my research.

Sorry Gadget, it was a long while ago, I think I read it as a comment or reply on a website. However it did make sense because my grandmother’s birth certificate (Shropshire) has her mother’s maiden name as Sarah Humphreys, but she was an Evans before she got married. On going back further I found that her mother was Harriet Humphreys before she married Moses Evans. My grandmother was the last of twelve children and although I haven’t checked them all, her first children have Sarah Evans as their mother’s maiden name (my grt.grandparents were together until old age).
