I am trying to find my mom, how can you find people?

I am 16 and i am doing this against my fathers permission, so it needs to be an easier way. my mom tried to contact me, but was unsuccessful because of my dad. i haven't seen her since i was three, i know her name is Maria Jean Winn (Winn is her maiden name, do not know if she has been remarried) she lives in oakland, Louisiana. please help! thanks(:
