Is Frankie truly gender neutral?

[NEC2678]

Or am I saddling my son with a girly nickname.
Frankie will only be a nn whilst he is young for everyone who will say he’ll need a more formal name on the BC

It's unisex now, though I think the female version is more recent.

There were singers (in the 50s and 60s) Frankie Valli and Frankie Avalon - both male - and an 80s song "Frankie" by Sister Sledge, about a boy. The name of the group 'Frankie Goes to Hollywood' was a reference to Frank Sinatra.

That said, the two Frankies I've come across more recently have been girls.

I think that traditionally it's more a boy's name (Valli, Avalon, Howerd) but more recently a diminutive for Francesca. I'd put a fuller name on the BC.
Not keen on it for either sex. It's a bit babyish for a boy and not very pretty for a girl.

For me it's more of a girls name.

I know loads of girl Frankies but no boys. They seem to go by Frank or Franklin. I think it's the long e sound that follows more traditionally feminine names (Sophie, Emily etc) But then again I know an equal mix of male and female Jamie and that has the same ending

I know an equal number of both!

I'd assume it was a girl BUT wouldn't give it a second thought if I found out it was s boy. I only happen to know female Frankies in real life.

The first Frankie I knew was a girl, 38 years ago (nn for Frances)

The only Frankies I've known since have been boys and they've been Frankie proper or nn for Frank.
