Fothergill's work improves upon William A. Crozier's efforts for Westmoreland County by including abstracts of wills of one entire volume (1665-77) omitted by Crozier, and extending Crozier's period of coverage (in Virginia County Records, New Series, Vol. I) by six years to 1800. About 8,000 related individuals are mentioned in 1,200 will abstracts, which typically give the name of the decedent, dates of recording and probate, heirs, executors, and, sometimes, the place of residence. Crucial for anyone doing research in Westmoreland County.
