| Death of a brother | John “John Jeffrey The Younger” JEFFREY about 1771 (Age 36 years) Note: According to documents found in the Surrey History Center, John Jeffrey the Younger mortgaged his property known as Beal-Wood in 1769. But in 1772 documents show that is brother James Jeffrey \"assignee of the Estate and Effects of John Jeffrey the Younger\" surrenders title to Beals-Wood as part of John's Estate bankruptcy. Thus John the Younger must have died about 1771. (Surrey History Center Documents 1294/2/27 1294/2/35)
