Hey guys! I really just made this account to ask this one question, I like the Nickname [name_f]Peggy[/name_f] for [name_f]Margaret[/name_f] too but I was wondering if you guys had any other good ideas for a full name to [name_f]Peggy[/name_f]? Thanks.
[name_f]Marguerite[/name_f] is a good one. Quite honestly, I love [name_f]Peggy[/name_f] as a full name itself!
Like @touslejours said, [name_f]Marguerite[/name_f] is a great option. It could also work with other forms of [name_f]Margaret[/name_f], like Margritte, [name_f]Margarita[/name_f], [name_f]Margo[/name_f], [name_f]Meghan[/name_f], and [name_f]Margareta[/name_f].
[name_m]Peregrine[/name_m] or [name_f]Prudence[/name_f]
Since it typically comes from [name_f]Margaret[/name_f]'s “M” and “g”: [name_f]Magdalene[/name_f], [name_f]Magdalena[/name_f], [name_f]Magnolia[/name_f], [name_f]Marigold[/name_f]
[name_f]Pelagia[/name_f] or Pelagie?
I love [name_f]Peggy[/name_f] on its own too!
I think it would work for [name_f]Penelope[/name_f], [name_f]Persephone[/name_f], [name_f]Calliope[/name_f], Penthea. I also like [name_f]Peggy[/name_f] on its own.
I’d love to meet a [name_f]Pelagia[/name_f].
Winnipeg could work if you like place names.
I’ll third the suggestion of [name_f]Marguerite[/name_f]. I’m on the fence with using [name_f]Peggy[/name_f] as a standalone name.
My Aunt goes by [name_f]Peggy[/name_f] and I’m pretty sure it’s her full name… She is also beautiful and very smart/ driven so to me I can see it on an adult as well as a little girl no problem! 
Maybe Megara or [name_f]Eglantine[/name_f], too?
