Freeholders are qualified voters. In other words, this list represents a portion of the male householders who were counted as eligible to vote. Other free, adult, male, property owners are not on this list. A voter list is much less comprehensive than a census document.
List transcribed and printed in DHNY volume 1: 370-71 (octavo size). This list was made "Pursuant to an Order of Court of Judicature held for the Province of New York on the Eleventh Day of June 720. Directed to Gerrit Van Schaick high Sherrif of the City and County of Albany; A Returne of the free holders of the said City and County." Signed: Gerret Vanschaijck Sheriff
The countywide list is found on the web in a variety of places. The original manuscript is in the colonial documents at the New York State Archives. A page from the manscript appears below.
