How to spell Molly?

Molly came out with a classic at dinnertime tonight.

It started out with me asking how a friends name was spelt.

Molly pipes up from the other end of the table "You can spell Molly three ways you know".

I'm thinking, yes, she's probably right; Molly, Mollie and (maybe) Molley?

She goes on to say: "Molly Shaw, Molly Kollmar and Molly Sullivan".
