Are you pronouncing the ending of
Rowena the same as
Georgina? If so, I think that
Rowena and
Georgina are too rhymey. If you're pronouncing
Rowena roh-WEN-a, I think that
Julian,
Georgina, and
Rowena sound nice together.
Elton sticks out a bit plus I automatically think of
Elton John. I definitely think that
Ambrose fits in better than
Elton. I also really like
Alden, which has a similar feel to
Elton, but I think it sounds nicer and works better with
Julian,
Georgina, and
Rowena.
