Pole Family Genealogy Forum
Good afternoon John. I am very sorry to say that I cannot help you on the connection of the Pettypool or Petypole connection back to the Pole/Pool family. However, I would suggest that you contact the nearest Mormon Family History Center (at any Mormon church). They may well have something on this in the library in Salt Lake City, and the information may well be on microfilm, which would be available at the local church.
I am also curious how your name became, once again, merely Poole. If your family came from the Pole/Poole family, then changed to Pettypool/Petypole, how did it get changed back again?
Good luck in your research.
