I believe this Gilbert will turn up on the Quartus Carley family I'm working on, as I believer the parent of Quartus of Amboy's father and mother is going to be (totally unproven yet) Joseph, Jr Carley and Sarah/Sally Gilbert.Joseph Carley, Jr being son of Joseph Carley, Sr and his wife Sarah/Sally Washburn.Please bear in mind, this is a work in progress, not proven.
