Mil names?

[Socks]

I would use it.. And let her think what she likes (Can you tell I dislike my MIL).. If you and dh like it that is all that matters..

What you like is all that matters, and if your MIL ever took the credit for it there would be no harm in saying that actually you always liked that name, it wasn't her doing!
But just while I'm having my 2 cents worth you would then have a Trent and a Nathan which together is a mens clothing label... if that doesn't bother you then go for it.
