I like both names they're very sweet. They are a bit too close to be used in a sibset I think. If
Josephine didn't start with the same
Jo- sound/letters and then add that it's so closely followed by the C/S that has that S sound. Another thing is that their style is a bit different,
Jocelyn is a a bit brighter and fresher sounding where as
Josephine is a bit older in sound. I think the contrast between the sisters names would be felt at once.
It's too bad too because they're both lovely names! Maybe
Josephine could be a MN for
Jocelyn's sister?
Some MNs for
Josephine just in case:
Josephine EveJosephine SadieJosephine Violet /
ViolaJosephine EvelynJosephine MaryJosephine EliseJosephine AliceJosephine Annabelle /
AnnabelJosephine RoseJosephine RuthJosephine RubyJosephine NoraJosephine Lily
Any you fancy? Many of those combos would work with
Josephine as the MN too. I hope this helps!
