According to web page "http://www.geocities.com/Heartland/Ridge/4207/d1/i0000251.htm#i252":
1. John Henry1 Pool(115) was born Muddy Creek, Rowan County, North Carolina June 10, 1776. John died April 7, 1856 Knox County, Illinois, at 79 years of age. His body was interred Knox County, Illinois, Cherry Grove Cemetery.
He married Temperance "Tempe" G. Lomax Illinois, Jan. 11, 1823. Temperance was born Boyle County, Kentucky May 22, 1802. Temperance was the daughter of Elijah H. Lomax and Rachel Hiatt. Temperance died Jan. 31, 1887 Abingdon, Knox County, Illinois, at 84 years of age. Her body was interred Knox County, Illinois, Cherry Grove Cemetery.
Tempe's birth year is one year off of what you quoted, but I'm confident this is the same person.Could not find anything on John Pool's parents.
My paternal grandparents were Rexford Shannon Lomax and Stella Pool, but I'm uncertain as to relationship with Tempe or John Pool.
