My research indicates that Solomon was born in Heidelberg, PA, around 1798. His father, (George) Jacob Horn (1775-1867) is on the 1820 Heidelberg, Lehigh Co., PA, census along with his brother Christian. Jacob Horn's parents were George Henry Horn (1756-1809) and Barbara Horn. Jacob is buried in the Bunker Hill Cemetery in Carbon Co., PA.
Solomon's birth/christening is recorded at the Heidelberg Union Church, Heidelbert Twp, Northampton Co., PA under 1801.
Solomon's marriage to Polly (Magdalena) is recorded at the Ben Salem Church in E. Penn Twp., Carbon Co., PA in 1824.
