Currently crushing on the name [name_f]Ursie[/name_f], but more as a nickname. I’m looking to find more possible full names other than [name_f]Ursula[/name_f], which I do love, but am concerned about the negative association with Disney.
What about [name_f]Ursulette[/name_f] or [name_f]Ursuline[/name_f]?
I love [name_f]Ursula[/name_f]! [name_f]Ursuline[/name_f] and [name_f]Ursule[/name_f]/[name_f]Ursulette[/name_f] are options as the previous poster said, but they’re still very like [name_f]Ursula[/name_f], so may as well go for gold and use it. Plus once people know YOUR [name_f]Ursula[/name_f], that will be their thought of Urusla 
One more thought is using something else for which you could get [name_f]Ursie[/name_f]…For example [name_f]Persephone[/name_f] (most Persephones get shortened to [name_u]Percy[/name_u], which rhymes with [name_f]Ursie[/name_f], so you could use [name_f]Ursie[/name_f] as a nickname for [name_f]Persephone[/name_f]).
I love [name_f]Ursula[/name_f]! At a stretch you could play the bear connection and call little Bernardette or [name_f]Bernardine[/name_f] ‘ursie’
[name_f]Ursella[/name_f]? Or [name_f]Thursa[/name_f]?
