Is the name Tatum feminine, masculine, or unisex?

If you heard the name Tatum, would you assume the person called that was female, male, or could go either way?

I’ve only known it as a girls name because of actress Tatum o’ Neal who’s actor Ryan o’Neals daughter

I would assume female and American and that the mum was a movie fan.
