I don't care for
Susannah but a lot of other people seem to like it.
You would know better than I would if it's a problem that your cousin's daughter is named
Susannah. Do you see her often? Are you two close? Do you think she would mind? I have a large family and I only see most of my cousins' children once, maybe twice, a year so it wouldn't be a problem. Lots of my second cousins have duplicate names. But that doesn't mean that your family has the same dynamic as mine.
I don't like the nn
Susie unless it's on a child younger than five.
Anna is nice.
