You have your great grandfather, Ernest Edwin Byam, who is #310, 8th generation, on page 255 of the book. He also appears on p. 175 listed as a child of Seth Ernest Byam, #186, 7th generation. Seth, in turn, also appears on p. 95 as the son of Alonzo Byam, #81, 6th generation. Alonzo is also on p. 49 as the child of David Byam, #36, 5th generation. You are now on the internet list that I have posted. Continuing back in "Descendants ...", you've now reached Chelmsford because David's father, Joseph, p. 26, #15, 4th generation was born there, buried perhaps in Lee. The next generations back are easy. BTW, please send me post 1975 information about your parents, siblings, and children at
