I am trying to find out if anyone has sucessfully linked their Landis tree to Hans Landis the martyr in hopes of doing so myself. The farthest back I can go is Benjamin Landis (1700-1781) who was a Mennonite and a farmer. He's buried in the Mellinger cemetery, East Lampeter Twnshp, Lancaster CO, PA. That is all I know of him. Anyone have any clues for me?
