I am also researching Groscost lines.
Jacob Groscost m. Martha granddau. of Theobold Sholas of Mt. Pleasant according to his will dated Sep. 5, 1788 probated Dec. 31, 1788 G 352.
Jacob was named in pension of his brother John in 1836
He was the son of John Groscost and Christina Noll.
WILL: John Groscost of Berwick Twp. will dated Sep. 23 1801 prob. Oct. 27, 1801 wife Christina children named John, Jacob, Elizabeth, Susanna and Joseph Little, Christina and John Knight, Daniel, and Mary.
I believe the Daniel Groscost who married Susannah Patterson is the father of Daniel Groscost so this would be a direct line and Patterson would be a direct line. Do you know anything about a Susannah Patterson? I did not realize Martha was a Patterson.
