Kanji reading of a name

Question

What reading would be used for "鮫" if it's a last name or a first name?

Answer 1

Well according to here there are 2 households with the last name 鮫{さめ} in Japan. Perhaps you met one of them? :)

However, if you change it to 鮫島{さめじま/さめしま} you can find many more households, like this women's soccer player: https://en.wikipedia.org/wiki/Aya_Sameshima
