I use familysearch because it has sources (except user submitted pedigrees which often don't). It's FREE, you can view, download, save, print what you find, and I don't have a subscription to ancestry.com

As for George, this might be him: I wonder if Oct is a christening/baptismal date and Sept is a birth date??? You would have to write the Town Clerk I guess to get a copy, and see what it says on the record. (Correct location/parents)
