I'd just use it, they'll get over it! It's a lovely name.
Me too. Stuff them, its a name they dont own it.
This is your baby, no one elses.

Sorry, this is something I am pretty passionate about. Most people would be honoured, or have it as tradition to reuse names within a family.
We have 3 Michael's, a Michelle and a Michaela (and 2 of them are siblings), and lots of names where there are at least 2 in the same generation.

Isabella Jane is about the only one I can think of. I prefer Chloe Elizabeth though
