Richmond County is a county located on the Northern Neck in the Commonwealth of Virginia. As of the 2010 census, the population was 9,254. Its county seat is Warsaw. The rural county should not be confused with the large city and state capital Richmond, Virginia. It was formed in 1692 when the first Rappahannock County was divided to form Richmond County and Essex County.
'Old' Rappahannock County was formed from Lancaster County on 11 December 1656. It functioned as a county until 1692, when it was abolished and split into Essex County and Richmond County. At the same time, Farnham Parish was divided into North Farnham Parish (Richmond County) and South Farnham Parish (Essex County.) The Rappahannock County records were retained by Essex County. The main reason for the division was the physical separation of the two jurisdictions by the Rappahannock River.
An anomaly of this division was that the parent county, and its court, were abolished entirely and substituted by two new counties and two new parishes.
Note: Westmoreland was reported with Richmond in 1800. Westmoreland's 1790 census boundaries were the same as those of 1810-1990.
