Peter DeHaven was born 1741 in Whitpain, Montgomery, PA to William DeHaven (1714-1784) and Hannah Cramer (1717-1786).  His occupation was yeoman and stonemason.  He was often confused with his uncle, Peter DeHaven II (circa 1719) who was also a stonemason before becoming a Philadelphia merchant.  It has been alleged that Peter was listed as a Tory during the early years, however on 15 Jun 1778 he took the Oath of Allegiance.  He served as a Private with the 4th Battalion, Pennsylvania Militia assigned to Thomas Mifflin's Brigade during the war.  The Brigade was raised 9 December 1775 at Philadelphia for service with the Continental Army.  It was assigned to Thomas Mifflin's Bigade on 26 June 1776.  Part of the unit was captured at Fort Washington 16 November 1776.  The regiment fought at Brandywine, Paoli, Germantown, Monmouth and the Sullivan Expedition.  It was furloughed 17 January 1781 at Trenton, New Jersey and disbanded 1 Jan 1783.  It is not known in which battles the DeHavens fought.  There are Pennsylvania real estate records indicating Peter owned and sold land in Whitpain Township, Montgomery, Pennsylvania around 1790.  Shortly after this, Peter and his family moved to the upper end of Back Creek Valley near Winchester, Frederick, Virginia.  He had received his share of 800 pounds from the sale of his father's plantation in 1786.  It is quite probably money that may have fallen into the category of post Revolution Currency, known as "Not Worth a Continental".  His migration to Virginia may have been prompted by the fact that the land was undamaged by the war and could be procured with a diminishing inheritance.  It is also probable that a stonemason could find more work.  About 1808 he purchased land near Winchester on Rte 608 which is currently Hunting Ridge Road, just west of Back Creek.  Peter's religious affiliations were likely with Boehm's Reform Church, Bluebell, Pennsylvania.  There is little information on Abigail.  Of this marriage, eight children were born.  Isaac (Revolutionary War Patriot) (1765-1838); Hannah DeHaven (1767-Unk); William DeHaven (1769-1800); Sarah Magdalena (Leannah) DeHaven (1772-1853); Rachel DeHaven (1775-1800); Jonathan DeHaven (1778-1837); Jehu DeHaven (1781-1837) & John DeHaven(1784-1859).  Peter died 1822 in Gainesboro, Frederick, Virginia.
