Also known as Marcus Groff. Mark Grove was the youngest son of a Mennonite family which had fled Switzerland for the Alsace region in France before coming to William Penn's colony in what became Pennsylvania. Christian was an early settler in the 1750's on the north fork of the Shenandoah River and was believed to have been Christian Grove's brother according to Forerunners: A History or Genealogy of the Strickler Famlies Their Kith and Kin, by Harry M. Strickler (Harrisonburg, Virginia: 1925), p. 116. However, he was also said to be Christian's cousin elsewhere. He was a member of a Captian Michael Reader's Company of the Continental militia during the American Revolution, along with Christian Grove. More details about Mark Grove can be found on Christian's page. There is also an unpublished history, written by Thomas Grove Frazier, which contains further information about the Grove Family.
