Per Richard A. Prewitt on page 20 of Moses Pruitt, Sr. & Rachel: Their Descendants (1997), we learn what became of Moses after his death:
"Moses B. Pruitt died in Armstrong Twp., Vanderburgh Co., IN on April 6, 1839, and was buried at the old farm outside Cynthiana, Indiana."
The birth date comes from the same source.
Moses married Phebe Williams in Warren County, Kentucky on 3 Jun 1805. David Benson was second. (Source: Warren County, Kentucky Marriages, 1797-1851 from the original marriage bonds and consents by Helen Thomas et al ).
