It's very rare to meet another Josiah. I've only done it maybe a couple times (irl, not counting online). One time I went to a house party as a teen and someone said "oh shit Josiah is here!" and the party cheered until they saw it was me. Someone said "wait, you aren't Josiah the rapper"

I never met Josiah the rapper. Sounds like he was doing pretty well for himself though!

I've met exactly one person with the same first name as me and she was in my class at school. I disliked her for reasons other than her (our) name, but I also never liked my name anyway
