In the Enchanted Forest, Neal was known as Baelfire and he is the son of Rumplestiltskin. Rumple became the Dark One when Bae was just a boy, and he hated it. He tried desperately to help bring his father back from the dark side and was lost to our world as a boy. He grew up alone, as Neal, and met Emma when they were both young adults (late teens/early twenties). They had a very Bonnie and Clyde type relationship living a life of crime, but they did love each other, even if Neal let Emma take the fall and go to jail for a robbery.
He did spend some time in Neverland as a boy after being kidnapped from the Darling House by Peter Pan, and he met Hook there, where Hook was like a foster father to him.
Neal is Henry Mills' biological father, though he didn't know Henry existed, and he finally gets to meet Henry when the family is reunited. I won't say anything else because it will give away the story!
