Also known as John Henry Brumback and Henry Brumback, The Pioneer in the history of the Massanutten settlement.

From Forerunners: A History or Genealogy of the Strickler Families Their Kith and Kin, by Harry M. Strickler (Harrisonburg, Virginia: 1925), p. 42:

From the Brumback families I learn 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... The Heistands moved from Shenandoah County to Ohio in 1804. A will of Jacob Heistand is recorded in Montgomery Co., Pa., 1769... The widow, Brumback above, was the mother of Henry Brumback, the ancestor of the Page County Brumbacks.

From Forerunners, pp. 181-182:

Henry Brumback of "Spring Farm," near Luray, b: 1739 d. 1799 estate in Rockingham Co. on "New Glasgow" near Mole Hill about 4 miles west of Harrisonburg....

Henry Brumback, the pioneer, had 15 children. They all went to Fairfield County, Ohio, except Henry, who remained in Virginia and left six sons and six daughters. Henry Jr. is therefore ancestor of all by that name in Virginia. He married Mary Grove, daughter of Mark. I understand that Mary's mother was a Strickler, 2nd wife of Mark. Jacob Strickler's first wife was a Kauggman and likely a sister of Henry Brumback's first wife. All of the early Brumbacks and Stricklers were nearly related, one way or the other.

The "Brumback Families" contains a complex record of the first family of Henry Brumback, the first, but does not extend to the second family. The first family left numerous descendants in Ohio, some of them becoming prominent. The family in Pennsylvania spells the name Brumbaugh. Ex-Gov. Martin Grove Brumbaugh is connected. John Strickler, son of Jacob of Egypt, married Barbara Brumback, eldest child of Henry. She afterwards married Samuel Kauffman. John Strickler makes John "Broombaugh" executor of his will, probated in 1802.

The second family of Henry Brumback, whose mother was Ann Strickler, consisted of seven sons and one daughter, Maria or Mary. I have been unable to locate the descendants of any except those of Mary. They all went to Ohio. Jacob and Tobias returned to Virginia and probably never married. From a deed dated 1818 we know that Samuel, Daniel and Christian were married at the time and was loving in Fairfield Co., O. Joseph and Matthew do not appear in the deed and therefore probably died young.

There also appears to be a confusion between Henry Brumback as father and son.
