I secretly love
Sheridan on a girl. I would absolutely consider it for use IRL. I like
Sher too. And
Sherry is kinda sweet in a "not quite vintage but still outdated" way- it's really the only name like that that I like.
I couldn't imagine it on a boy until RIGHT before I read your post, lol. It was weird I went through this thought process in my head wondering about what gender you'd be asking about; myself assuming female since that's how I've always considered it but then had to imagine you could be asking about it for a boy.... And I never thought I would but I kinda like it, or at least don't mind it. Although it is a bit pretentious sounding
