The minute books of the old Virginia courts herein transcribed cover the District of West Augusta and Yohogania and Ohio counties during the period when Virginia claimed and exercised jurisdiction over what are now the Pennsylvania counties of Washington, Greene, Fayette, Westmoreland, and Allegheny. The minute books contain, in addition to land titles, transcripts of legal instruments of immense genealogical value, such as deeds, mortgages, conveyances, probate records, administrations, contracts, suits, judgments, and oaths of allegiance--through which are identified thousands upon thousands of the early settlers of the Monongahela Valley.
