So this is just some insight to the Andrews bloodline.

So the furthest back I'll go is to:
Horacio Andrew: the First Andrews boy. Born to a family so dysfunctional he left. He changed his name as soon as he could. He kept his First name but he cut ties to his parents when his last was changed to Andrews. He met the love of his life Dana (last name not necessary cause she became an Andrews). Together they had three beautiful children. Marco, Mario, and Maranda Andrews. Marco and Mario were Twins and Maranda was their younger sister. The three grew up and started their own families. Marco met a beautiful woman named Sandra and conceived the Twins Geronimo And Giuseppe, though they go by Eris and Shawn. Mario met a woman named Natasha and had a Girl named Marilyn. Maranda met a nice man and Had a pair of twins of her own. One was a white haired boy named archer and the other was a beautiful blonde girl named Ariel. 

As of now I don't really wanna go into detail of their children cause Eris got busy.
