Relation

I had searched on my name on google to see if my privacy settings were in place for some of my sites. However, this link about Rachel Eliza Harpenau-Van Dam came up number two in my search. Harpenau is not a common last name, and I was wondering if there was anyway to find out whether I am related to this woman. Any information about who she is would be greatly appreciated. My email is rcharpenau@yahoo.com.
