You would honor your DH's mum by using Molly? Its up and coming name at the moment, two of my friends have used that name. I prefer Molly to Holly as it is more girlish. If you call me a bit old fashioned lol.

I like Amy better as it just rolls off the tongue better. Love Love Amelia.

Amelia Renae- love love
Molly Renae- very nice
Amy Renae- is ok
