For those of you who believe that Jesus had children with Mary Magdalene and married her,?

do you think the St. Clair family today would know anything about this? I know that their family is tied into the rumor that Jesus married Mary Magdalene and had children with her. Rosslyn Chapel was featured in the Da Vinci Code, and I have found that church to be linked to this rumor through research of my own. I'd love to know if anyone in the St. Clair family still knows anything about this, and what they know.
