What could the name Margo be short for?

Question

I love Margo, but not sure about using it as a full name.

What could it be short for (other than Margaret)?

Do you think it sounds like a legitimate name or just a nickname?

Answer 1

I think it’s a legitimate name by itself and is very pretty

Answer 2

Marigold, probably. Only name I can think of besides Margaret.

Answer 3

Definitely its own name. Could be short for Marguerite too. I prefer it with a t on the end.

Answer 4

MARGARET, MARGUERITE,

Answer 5

Marjorie /Margery. Margo is also a full name.
