This is a must for your Virginia to do list. Search in the Library of Virginia catalog for "[family surname name] family bible. For example: "Leftwich Family Bible" or "Ward Family Bible". Several of these have online images or typed transcripts and other surprises like obituaries. Look carefully for a URL in the library catalog entry. Some are in .PDF format and others are in .jpg or .tif images.
I found one County Register listed as a Bible Record: the title of this record is "Dalton Family, 31 leaves, photocopies,Halifax and Pittsylvania Counties, Virginia, 1821-1847. The register notes births, deaths, marriages, hangings, murders, and people moving away or returning to the area."
