When I hear someone say they’re from Philly, I assume (& hope) they were born here. I wouldn’t say I’m from somewhere I wasn’t born.. If you were born in NYC and moved to Philly as an adult, you’re not from Philly, you’re from NYC. You could say I live in Philly, Philly is my home… but you’re not FROM Philly. If Philly didn’t make you who you are today, you’re not from here.
