Which Jesse are your descended from? Jesse
Montgomery or just plain Jesse? To fine where you are in the Seaver line you need to provide more information. Surely you can find the names of your Seaver grandparents, and their dates of birth, and places of birth if possible. The same applies to your parents. I suspect you and your siblings know your parent's names and place of marriage. Or you can research it. Surely aunts and uncles will provide some information helpful to searching out your line.
