In 1876, Union Army veteran Thomas Woolfenden and his wife Isabelle purchased 140 acres near Chopawamsic Creek County while continuing to live in Baltimore. In 1885, the Woolfendens settled in their new Prince William home. The small community was originally named Voy after the local postmaster, and at that time a schoolhouse was being used by local Baptists as a place of worship. The Woolfendens donated an acre of land for a new church, completed in November 1886 and named Belle Haven Missionary Baptist Church in honor of Mrs. Woolfenden. The farming community became known as Kopp in 1901 with the establishment of a new post office. In 1942, the expansion of Quantico Marine Corps Base through eminent domain abruptly displaced the community, and all structures were demolished. The only vestige of Kopp today is Belle Haven Cemetery a short distance to the west, and family members continue to use the cemetery for burials.
