I dont mean to be mean in any way when I say this, but I know it is going to sound mean. When I was looking at the pictures of the cast, I thought to myself....Jenny stands out from the rest of the group when it comes to looks. The women are all very attractive and I dont really think she is. Usually, it is not like the producers to cast all beautiful women but one for a show like this, unless it is based around the theme of the show.
I know that sounds mean, but from first glance she immediately stood out to me.
I definitely think she is one of the relatives but I have no idea who she is related to, but I think Rob might be on the right track!
