The following 2013 photo shows the handsomely-inscribed sandstone tombstone of Henry Boucher at the Union Cemetery in New Centerville, Pennsylvania, along the Mud Pike. For the reasons stated here, I believe that Henry is the brother of Susanna, wife of Michael Korn, Sr. of Southampton Township, Somerset County, Pennsylvania.
The tombstone inscription states, "In memory of HENRY BAUCHER who was born March 10th 1759 in Berks Co. Pa. & died Nov. 19th 1834 aged 75 yrs 8 mo. & 9days. And merciful men are taken away, None considering that the righteous Is taken from the evil to come. He shall enter unto peace: they shall rest in their beds each one walking in his uprightness. Isaiah. Ch. 57".
