The Lancaster Mennonite Historical Society has copies of a bible that belonged to Abraham Mumma and was presented to him in 1813, probably at the time of his marriage to Veronica Brandt. The cover, inscribed in German, indicated it was in Rapho Township of Lancaster County. Images of the bible can be found & viewed in the Mumma Archives.
