Beginning in 1795, a person could declare their intent to become a citizen at any time and in any place after they arrived in the United States. Prior to the Naturalization Act of 1906, the naturalization process primarily occurred in local and state courts. Declarations of intent were the record by which an applicant for U.S. citizenship declared their intent to become a citizen and renounced their allegiance to a foreign government. This document typically preceded proof of residence or a petition to become a citizen by two or more years.

Rockingham County was named for Charles Watson-Wentworth, second marquis of Rockingham, who supported the colonies during the years before and during the Revolutionary War. The county was formed from Augusta County in 1778. The county seat is the city of Harrisonburg.

A courthouse fire in 1787 destroyed primarily wills and estate records. In June 1864 during the Civil War, court records (mostly volumes) were removed from the courthouse and loaded on a wagon to be taken to place of safety on or beyond the Blue Ridge. The wagon was overtaken by Union troops near Port Republic and set afire, which was put out by local citizens. Many order books, deed books, will books, and fiduciary books, however, were lost or severely damaged by the fire. The loose records that remained at the courthouse were undamaged. Pre-1865 records including deeds and wills were rerecorded following an act of assembly passed in November 1884.
