Αngel is a funny one. For Anglo Americans I’ve only known girls by that name, but with Mexicans (born in Mexico) I’ve only known guys by that name as they have Angela for their girls.
Yeah there are a few names that become "unisex" only in the aggregate, with differently gendered usage across cultures-- Alexis is another I can think of, it's a girls' name in the US but a boys' name in most other countries.
Also Sean. I think the Irish prefer Sinead or Siobhan instead for naming girls.
Another I think is Rosario. A male name in Italy, a female name in Mexico/Spain.
Similarly, “Andrea” is male in Italian but female in German.
My friends from Poland adopted a female cat named Sasha and were adamant that Sasha was a male name.
