How do people think about this?
We are planning names, not sure of the sex yet.
I am Welsh and dh is English. We live in London.
If we have a girl, I really want to call her Gwenllian, and will call her Gwen. This was my grt grandmas name and I think Gwen for a girl is lovely 
Dh really isn’t keen. He doesn’t really like welsh names and prefers more mainstream/english/popular names like Olivia and Lily. But these are not my cup of tea for my kids.
