Peter and his son Isaac were both Revolutionary War soldiers with the rank of Private in the 4th Battalion Pennsylvania Militia. The 4th Pennsylvania Regiment, first known as the 3rd Pennsylvania Battalion, was raised December 9, 1775 at Philadelphia, Pennsylvania for service with the Continental Army. The regiment was assigned to Thomas Mifflin's brigade in the main army on June 26, 1776. Part of the unit was captured at Fort Washington on November 16, 1776. The regiment fought at Brandywine (1777), Paoli (1777), Germantown (1777), Monmouth (1778) and the Sullivan Expedition (1779). The regiment was furloughed January 17, 1781 at Trenton, New Jersey and disbanded on January 1, 1783. It is not known in which battles the two DeHavens fought.

Abigail died in 1827 at the age of 81 and Peter died in 1822 also at the age of 81. They are both buried in the Back Creek Quaker Cemetery, Gainesboro, Frederick Co., VA as well as their son Isaac. Descendents erected a modern gravestone for Peter and Abigail DeHaven in the old Back Creek Quaker Cemetery. The late Robert Unger arranged for the Veteran's Administration to donate a tombstone for this Revolutionary War veteran's grave, and Edward Shirley was responsible for erecting the stone. No one seems to know why the DeHavens were buried here, in that neither were Quakers. One of their daughters, Leanna(1772-1853) married Quaker David Adams, and this may have been a connection. The cemetery is now maintained by the United Methodist Church, and burials are still made at this site.
