JACOB STRICKLER OF EGYPT

He died in 1784, leaving 13 children: 1st 6 by 1st wife...

Jacob Strickler lived in lower Egypt on part of the 1000 acre tract his father Abraham purchased of Jacob Stover. In 1755 Fairfax gave him a deed for his part of 1000 acres, his father having derived his title from the Colony of Virginia and it having been discovered that this land was on the Fairfax Dominions. Jacob Strickler's home, combination fort and dwelling, still stands in Egypt. It has been described. Draw a line from the mouth of Mill Creek to Strickler's Knob and this line will pass over Jacob's house and not miss his brother Joseph's house very far. He was buried opposite the mouth of Mill Creek on the brow of the first bench that rises from the lower bottom and on the northern edge of a depression that leads down from the upper to the lower ground. Three lone cedar trees stand here now. It is just north of a line fence between J. C Burner and J. C. Bowers. Here, it is presumed, they buried Abraham, here they buried Jacob and his two wives, and here they buried John, the eldest son of Jacob. Only one headstone remains standing at the foot of the three cedar trees to mark the last resting pace of John [ft. n. Mr. Wm. Lee Strickler, of Lake Bay, Washington, tells me that he remembers when a fence surrounded this graveyard and ten or twelve headstones, mossgrown, were within the inclosure. He thinks that some of these stones are probably in J. C. Bower's barn wall]. John lived in the old home he inherited from his father Jacob. John's widow married Samuel Coffman, and they moved to Linville Creek, Rockingham County, Virginia. Nancy Kauffman who married Jacob Strickler was likely the daughter of Martin Kauffman who died in 1749.

I have an old note dated March 14, 1750, addressed to Jacob Strickler, Sr., and signed by Sert. Tho. Baker in which the later promised to the former a sum of money. Cousin Selina Strickler gave me this note. She also gave me one which proves that Jacob had a brother Benjamin. It is dated Feb. 12, 1767.

From the Brumback families I learned that Jacob Heistand married a widow Brumback., that Jacob drowned by the upsetting of a canoe in the Shenandoah River and his family moved to Fairfield County, Ohio, near Baltimore, and that they had the following chrildren: Jacob, Rev. John, m. Barbara Strickler, and had ten children, Rev. Abraham, Rev. Joseph, Elizabeth, m. Jacob Stouder, Maria, m. Jacob Bixler, and Rev. Samuel, Bishop of the U. B. Church, and Barbara, m. Boyer. The Heistands moved from Shenandoah County to Ohio in 1804. A will of Jacob Heistand is recorded in Montgomery Co., Pa., 1769. Barbara is likely the daughter of Jacob or Joseph Strickler. Marriage records of Shenandoah show that Barbara Strickler m. John Heaston, June 8, 1789. Magdalene may have been the widow of Jacob Strickler, dec'd.

Here is an early deed that throws additional light on this family. In 1798 Elizabeth Heastant, window of Jacob, dec'd., Jacob Heastant and Mary his wife, Abraham Heastant and Magdalene, his wife, Jacob Stouter and Mary, his wife, Christian Pilser and Elizabeth, his wife, John Heasant and Barbara, his wife, Frederick Lucas (Ducas) and Magdalene, his wife, Joseph Heastant and Samuel Heastant, of the first part, convey unto John Strickler, Sr., of the second part, a tractof land that was conveyed to Henry Heastant, dec'd (1798-L.-p. 225-Woodstock).

These are the heirs of Jacob Heastant, dec'd, evidently...

From Old Homes of Page County, Virginia, by Jennie Ann Kerkhoff (Lauck and Company, Inc., Luray, Virginia: 1962), pp. 5-6:

The large, square old house in what is now known as "Egypt Bend" west of the Shenandoah River has long been a landmark in the Valley and the subject of many stories and tales. For it is on this property that Abraham Strickler, ancestor of most of the Stricklers in Virginia, located when he came to this Valley. - The old house, however, is believed to have been built by his son, Jacob Strickler. On this property may be found what is believed to be the oldest mill in the Shenandoah Valley, the well-known Strickler monument, and an Indian mound so interesting as to have attracted the attention of the famed Smithsonian Institute and last, but by no means least, the house and fort itself.

Fort Egypt, an immense square building, is constructed of giant logs of maple, walnut, pine and oak. and paneled in some rooms with boards 15 to 20 inches wide. Some of the rooms are paneled in solid walnut and the doors are made of these wide boards with the well-known "H and L" (signifying "hope and love") hinges, used by early settlers as a sign of "good luck".

A huge stone chimney rises from the center of the house and there are fireplaces in several of the rooms. The fireplace in the kitchen is eleven feet wide! There are also a number of square holes in the walls used for burning pine torches for light.

Over the doorway in one of the rooms is penciled (or charcoal) the name of Jacob B. Stover, August 1813, in a fine, old-fashioned script.

Beneath the house is one of the best-preserved fort-cellars in this area. The outer cellar, which is reached by means of an inside stairway and through a doorway under the porch. is a very large room extending the length of the house. The outside walls of this room are constructed with the familiar loop-holes through which the defending settlers might shoot at attacking Indians. The ceiling of this room is exceptionally interesting because the old logs, interwoven with straw and then "sealed" with mud, are clearly visible.

The inside fort, or "the fort of last resort" is a smaller room adjoining the outer fort. A huge wooden door with hand-made latch, leads to this room. Inside are more loop-holes, a spring which provided water, and hooks, apparently used to hang hammocks or perhaps supplies in case the settlers found it necessary to stay in the fort for any period of time.

The loop-holes are quite interesting to see. The inside where the defending settler stood with his gun, is quite wide enough to allow a man (or woman) to stand and shoot without being crowded. The hole slants upwards and out and is narrow at the outside, probably about eight inches wide and twelve inches high, thus cutting down the size of the target for the attacking Indian sharpshooters.

"Fort Egypt," as Jacob Strickler's home is now known, is still in fine preservation, and its present owners also maintain a informative website with many interesting pictures of this structure and its surroundings
