Maitland Ward is an American actress. She has starred in various films and shows, including Boy Meets World (Rachel), and White Chicks (Brittany Wilson).
Personally I see the name, Maitland as a female name. It can be shorted quite nicely too Mati, Matey, Matie. It would make a lovely name for formal use and simply Mati for short or theirs quite a few other alternatives you could use.
