Sullivan

Thoughts on Sullivan?
Sully as a nn

Love it, but with our surname it would sound like an Irish estate agents.

I’m hoping for another girl so I can use Iseult nn Sully

I really like it, quite unique too. And monsters inc is awesome too!

Not keen on Sullivan but Sully is really nice!

Sully think Monsters Inc
Sully to dirty something.
Sorry OP don't like this name for a child.

I don’t know anyone that would use that term for making something dirty.

Regarding the surname thing, boys will always have nicknames, names shortened, or some boys get called by their surnames. It’s really not a big deal.

I don’t know anyone that would use that term for making something dirty.

Possibly not 'to make dirty' but it is in common enough usage meaning "to spoil" or in connection with "ruining a reputation or good name".
It's quite a negative word.

I am of the same opinion as BackForGood
