I found this additional source which list George and Racheal as Daniels Parents, his siblings as Becky Ann, Jacob, Polly, Rudolf and Daniel, and references Rulief Schenck a soldier of the Revolutionary war who served under Washington and fought at the battle of Monmouth as his grandfather.

Relevant info is on page 490-495
Again if anyone can find a additional information it will be greatly appreciated.
