Jan Clement emigrated from Germany to New Amsterdam in 1665. He married Maria Bouquet and they had five known children. Descendants and relatives lived mainly in New York, Ontario, Manitoba, Texas and California.
The book rings with the names of early inhabitants and prominent citizens. For the genealogist there is the important and wholly fortuitous list of tithables of Pittsylvania County for the year 1767, which enumerates the names of nearly 1,000 landowners and property holders, amounting in sum to a rough census of the county in its infancy. Additional lists include the names, some with inclusive dates of service, of sheriffs, justices of the peace, members of the House of Delegates, 1776-1928, members of the Senate of Virginia, 1776-1928, clerks of the court, and judges.
