One of the very cool benefits of putting research on the Internet is the instant gratification of input. Collaborating in this effort is my beautiful cousin Char whom I am indebted for her copious collection of census information on the many Pierces of Delaware County.
The following is info she had about William Henry Pierce and I'm happy to add to his profile. The end result of neatly written biographical accounts, accompanied by sources for information, will make a nice booklet.
Willam Henry is listed on the 1850 census living with his uncle Thomas Forsythe.
