Randy, Thanks for the response. I have done research in this fabulously informative book. Giles Slocum #239 was Frances' oldest brother and was the Slocum who actually witnessed the fratricide event while he was hiding on Monockonock Island during the Wyoming Valley Massacre, 1778. (This was the fratricide between Henry Pencil (a patriot) and his brother John Pencil (a Tory)). Henry's name is on the monument at Forty Fort in Wilkes-Barre today. I have resources that state Slocum #239's grandson Giles (Slocum #603) also told several people this story. I see that Slocum #603's children moved to California. Has this fratricide story been passed down to other Slocum's? Maybe written down in dairies or journals? I am descended from Henry Pencil (now spelled Pensyl) and am trying to fill in some history in our genealogy.
