We can also exchange research using this site, as well as here at genforum. I will be happy to exchange email addresses so we can exchange research by email, if you would like.
As for the "history books" about the Ralstons; William Ralston of that Ilk was a Covenanter in Scotland during King James IV's reign and helped spread the Presbyterian religion across Scotland. He spent time in prison over this. This website has Ralston information which you may have already known about, but I will post it here.
