From Forerunners: A History or Genealogy of the Strickler Families Their Kith and Kin, by Harry M. Strickler (Harrisonburg, Virginia: 1925), p. 321-322:

Isaac Strickler of Locust Grove.

Fort Massnutten.

...The fact that Isaac Strickler owned the Benjamin Strickler lands led me to believe that he was the son of Benjamin, but after discovered facts prove that he was not.

Tradition in the family does not state who the father of Isaac was, but it does state that he came from Pennsylvania with his uncles, Jacob, Joseph, Benjamin and John.

In 1761 Isaac Strickler received his share in the 1000 acres purchased from Jacob Stover by Abraham Strickler, from Lord Fairfax. This fact proves that he was not a son of Benjamin, and it also proves that he was either a son or grandson of Abraham, the pioneer. The language simply states that Isaac is entitled to his share by descent from Abraham, and the fact that the deed does not expressly state that he was entitled to a share as one of the sons of Abraham would indicate that he was a son of a deceased son.

Furthermore, the Miley Notes have the following to say:

"Susan Brubaker, daughter of Abraham and Barbara Brubaker born July 17 ----. She was the child that her mother took with her into the field to inform her father of the Indian's approach in 1758. Susan married Isaac Strickler, son of Abraham Strickler who lived in Pennsylvania." From this circumstance we know that Susan Brubaker was born prior to 1758. The next child born to Abraham Brubaker, according to Mr. Miley, was in 1761.

This would indicate that Abraham, the pioneer, had a son Abraham who remained in Pennsylvania, and whose son Isaac came to Virginia, unless Mr. Miley had in mind Abraham, the pioneer, in speaking of the father of Isaac.

Isaac Strickler lived in Massanutten. He built the stone house there which still stands. It has a fort cellar and has been described. When his son John lived here it was known as Locust Grove. Isaac was a large land owner, and his holdings seem to have included all the lands of Benjamin Strickler, after the latter's death. There is a quaint inscription, in German, written on the chimney, in the attic of the old stone house, which I am unable to make out. There is a date, 1791, written there also, which I first inferred was the date when the house was built, but I am sure the house was built much earlier than this, probably as early as 1760, certainly during or soon after the Indian raids, following the French and Indian Wars, 1755-1763, although some think the house was built in 1791 because of the above date. The fort cellar may be older than the house.

Isaac Strickler died in 1817 and is buried on the old homestead, not far from the old stone house. His son John is buried here also. There is a very old stone here with the following inscription: "I. Strickler, dec'd May 1, 1817." He left a will in which he mentions his wife Catherine, daughters, Elizabeth, wife of John Burner, Nancy, wife of John Beaver, step-daughter Mary Beaver, sons John and Jacob. He refers to his unfortunate son, Jacob, who was with the army in Canada, as being reported killed, and wills his share to John Brubaker in trust for him should he return. The slaves are to be drawn by lot and not sold.

Susan Brubaker, Isaac's second wife, was the daughter of the Brubaker mentioned by Kercheval in his history of the Valley, in relating the story of the Indian raid on the settlement in Massanutten. Brubaker's family was saved by the alertness of his good wife, who insisted that she saw Indians on the mountain not far away.

The Virginia Census of 1783 gives Isaac a family of five. This did not include his children as they were born after that date. It may have included other children who died young or white servants or relatives in the household. It may have included Jacob as we do not have the date of his birth.

Mrs. Virginia S. Milbourne, of Charles Town, a descendant of Isaac, informs me that there is a tradition in the family that Isaac was suddenly stricken in the field, that he tried in vain to make them understand something about leather breeches full of silver dollars that were never found, that he was a great singer, and that the superstitious could hear him singing about the old home long after he was laid to rest.

Isaac's will was made in 1814 and probated in 1817. The witnesses were Daniel Beaver, James Modisett and Wm. R. Almond. John Strickler and John Beaver qualified as executors and gave bond in amount of $15,000, with Wm. R. Almond and Joseph S. Spengler sureties.

Isaac Strickler was a member of the Virginia Legislature in 1806. His will provides that his slaves shall not be sold but drawn by lot by the children. There were nine slaves, the highest value placed on a slave by the appraisers was $550.

The lands of Isaac are divided among John Strickler, John Beaver, and John Burner. Jacob does not appear.

Peter Rothgeb conveys to Isaac Strickler and Abraham Spilter 170 part of 400 acres, patent tract, laying on both sides of Mill Run, lately the property of Jacob Rothgeb. The grantees convey same tract of 170 acres to Jacob, son of Abraham Strickler, dec'd.

Isaac was a large land owner. He owned 550 acres on the mountains back of Egypt, and other large tracts besides the Locust Grove tract. He also owned a large portion of the Benjamin Strickler estate.
