Girls name to go with BILLY? And no, not Milly...

[Picante]

Quite like either starting with the same letter, or ending with the same sound (i.e. 'eee').

So far have...

Molly
Maisie
Bessie
Betsy
Betty

P.S. Billy is officially a William so I guess he might change to Will when he's older!

Phoebe
Evie
Daisy
Carrie
Annie

???

I love Betsey, but not sure about it with Billy.

Is it too cheesy to have two names that sound so similar then?

Libby
Lottie
Hattie
Mattie
Maddy

--all have decent long official versions that go quite well with William

Billy & Evie
Billy & Caitie ( Caitlin)

Think you need to avoid another "ll" eg Molly,Holly,Tilly etc

your last three are going to sound silly with Billy I think you need to avoid another 'cutsie' name, Billy is more of a nickname so you need to think away from nicknames imho.

Anne?
Annie?

Billy and Ellie (Eleanor)

Thanks... I'm really drawn to Maisie at the moment. Just got to convince dh!
