I'm biased as DD1 is Iris Katharine

I quite like Frances - but I do think it sounds a bit manly. However I think Iris Francesca sounds great!

Frances is very very smart, a lovely name and not over used.

Would go with lots of lovely middle names

Frances Elizabeth
Frances Boudicca
Frances Eleanor
Frances Soraya
Frances Rosamund

Frances Amelia Ward?
Francis Rebecca Ward?
Iris Helena also sounds good to me.

I think Frances and Iris are both nice names.

I really like Iris.

Frances sounds to me like a boys's name - don't know why though....Perhaps because I know a Francis?

Both are nice although I think Iris is prettier and personally prefer that. It is more currently popular though, whereas Frances is more an all time classic name and not coming up very popular these days, it will be more rare amongst their age group if that is something you want to consider

I LOVE Frances. My DS has Francis for a MN and I wish I had saved Frances for his sister.

I like Frances a lot

Iris Franchesca Ward

Frances is beautiful.

I like Frances (and Fran as a nn, although most of the Frances's I know are known as Frances). I don't think there are many around, whereas Iris (also nice) is more in the old lady theme, and I've seen suggested here quite a bit.

Rhythm wise I think a single syllable name in the middle would be best. There was a thread the other day about single syllable names there might be some good ideas there:
