I think it is a beautiful name. The combo is wonderful & I can't think of another middle name that sounds as good as Ann.e with it. Just tell your mom you'll name the next one after her. (TIC if you are done with having kids)
I understand the whole family name drama. MIL is ALREADY suggesting names from her family, and I flat out told her that this child will have a name that honors someone on my side of the family, because J's middle name is FIL's name for pete's sake. I think that when you announce it, you can just say that it was important to you to honor your Grandmother, so her name is _______ and leave it at that.
