In 1755, Nicholas was captured by the Indians at the approximate age of 12.  Five years later, in 1761, at the approximate age of 18, the government advertised in two July issues of the newspaper Pennsylvania Gazette that families should come get their children as they were returned from their captivity.  (Letter from General Amherst to the Governor regarding the return of Nicholas and the other children is included at this link.)  If Nicholas was born in 1723 as is erroneously listed in Della Reagan Fischer's book on the Old German Cemetery, as being from the tombstone of Nicholas, he would have been age 32 when taken by the Indians and 38 when returned.

Will of Nicholas Silvius of 22 July 1802.  Nicholas states in his Will that "Baltser Stehly" owed him money on a bond.  A deed dated 11 November 1796, recorded at the Northampton County Recorders Office 21 February 1797, Book C-2, p. 501, shows that a Baltazar Stehly bought 130 acres of land from Nicholas Silvius.  This proves that Nicholas and family were from Northampton County, specifically Moore Township.
