Died: 1827 Place: Holden, Worcester, Ma
Note discrepencies with my Jabez. Very suspicious how similar are the birthdays, and have been unable to confirm that this Jabez died in Holden 1827. Seems much more likely that all 3 brothers went together to Chautauqua. Jabez was an uncommon name, so at the very least, they were related.
