I too keep our names to just us for similar reasons. If it's what you like then no one should tell you otherwise (except for maybe DH ) I haven't been too keen on a couple of names i've heard in the past but you grow to love them as you get to know they baby/child/person.

I have a friend whoes Grandparents called her a totally different name to what she was given at birth because they didn't like the name her parents had chosen for her. But they got over that eventually...
