I would also be interested to see the connections from Roger Gum and Matilda Holcomb. I have Cornelius, Jesse, Timothy, and Alice listed as their children and I have more details on Jesse's desendants as well as Matilda's ancestors.
As far as ancestors I have go, from an email source, I have Roger's parents as John Gum and Mary Dice. Roger appears to have a brother, Leonard.
John Gum's father was also John. I don't have his mother's name. There appears to be 6 sons. I would be interested in seeing how this ties back to any names in the "Leaves of the Gum tree" book which I'd be interested in buying. Any recommendations of a seller who might carry it?
