J. Frank Faust (Jacob Frank Faust), for whom the school was named, was my great uncle. Here is his info:
Birth 21 AUG 1890 in Pennsylvania (probably Franklin County)
Death NOV 1978 in Shippensburg, PA at Menno Haven Retirement Home
Parents: Jacob A Faust, b. April 1848, and Jennie O. Hoch, b. Oct 1852.
His siblings were: Nellie, Thomas Herbert, Carl B, Samuel Leroy, William C, Mable J, and Paul Bertrand Faust (my maternal grandfather).
Spouse: Margaret. They had no children.
His father Jacob did not have any siblings named Sarah, so I can't find a direct connection, although I'm sure all the Fausts in that area of PA are related one way or another. Jacob's father was Samuel Faust (1806-1883); perhaps Sarah was the daughter of one of his 9 siblings. If you know either of her parent's names, or have additional questions, please feel free to contact me at firstname.lastname@example.org
