There is conflicting information on this. I have one paper that lists them as living in Lancaster. 2 others on the baptism of Andreas' son, Solomon, has him baptised at Warrick Congregational Church in Lancaster (1745) -- 3 other children were baptised there too, John Jacob (1742), Joseph (1747), and Susanne Elizabeth (1748). Another has Solomon baptised at Emmanuel Lutheran Church in Brickersville, Lancaster County, Pa.
If you find out any more on Andreas, please let me know.
