I have yet to find my connection to this Decker family. My 2nd great-grandfather, Charles Gilbert Decker, was born in Carbondale, Pennsylvania, abt. 1863. He lived in Warwick and Port Jervis, New York, and died in Walden, New York in 1909. His widow, Lydia Decker, lived in Hamburg, Sussex County, New Jersey - all towns associated with this Decker family.
