All of your combos flow well, so I think they all work.
Ursula Amy,
Ursula Thisbe,
Ursula Florence, and
Ursula Marianne are my favorites. The softness of
Amy really balances out the combo. For the most part, I prefer softer names with
Ursula. Although I'm drawn to
Bronwen, I think that
Ursula Bronwen sounds too harsh.
Ursula and
Gretchen go together well, but
Ursula Gretchen is much too harsh for my ears in English. It sounds nicer in
German.
I knew an
Ursula Claire. I think that combo flows nicely.

Dagmar isn't a soft sounding name, but I like it, and I think it goes nicely with
Ursula.
