From Forerunners: A History or Genealogy of the Strickler Families Their Kith and Kin, by Harry M. Strickler (Harrisonburg, Virginia: 1925), p. 182:

Adam Strickler says, in one account, that Catherine Strickler, daughter of Jacob, married Brumback and was the mother of Tobias and Jacob and in another account that she married John Brumback and had two sons, Tobias and Jacob, and owned the valuable property known as Spring Farm.

The Brumback genealogy, according to "Brumback Families", states that Anna Strickler married Henry Brumback of Spring Farm and had eight children, among them Jacob and Tobias

It court records she is called both Ann and Nancy. All sources of information agree that she was the mother of Jacob and Tobias Brumback and that she lived on Spring Farm, and Adam says she was the daughter of Jacob Strickler. Her full name may have been Ann Catherine and her husband's full name may have been John Henry. She was the right age to have been the wife of John Brumback, son of Henry, but his wife was Elizabeth Rothgeb and he had no sons named Tobias and Jacob.
