John Stock was born 1 February
1757. The "History of Cumberland and Adams Counties,
Pennsylvania", 1886, says that he was born in Germany and settled in Earl
Township, Lancaster County, Pennsylvania. Another source says that he was
born in Adams County, Pennsylvania. He purchased land from Leonard Mumma
that was still in possession of John's grandson in 1888. John married
Leonard Mumma's daughter, Anna Margaret "Agnes" Mumma, who was born 17
August 1767. I am descended from their daughter, Lydia, who married George
W. Hoffman on 17 November 1831.
