Ok, I believe the Wagon Train leading Fisks were the sons of James Byron Fisk and Jerusha Theresa Loveland. Co-incidentally they also had a son named Andrew Jackson Fisk. The other wagon train leadingbrothers are James Liberty Fisk, Robert Emmett Fisk, Van Hayden Fisk and possibly Daniel Webster Fisk.
These Fisks are originally from New York and Massachusetts before that. There is no indication that this branch ever lived in Connecticut.
