I think Nicki and Isabel and Courtney are cousins, their Mom's look incredibly similar!

They have the same nose. THEY HAVE THE SAME NOSE. Even their smiles are similar. And they both have glasses. I'm not too sure if you could count Maureen (Woman on the right) As a blond though. Courtney's middle name is Deoborah and that's specifally a name from the Bible. You know, maybe Maureen could have had an Chirstian upbringing then... Or maybe this could be the result of a generic design. Even though they're 14 years apart, I can imagine the twins and Courtney as best friends!
