I can share a little information on the Revolutionary War service of Andrew Cop, extracted from his pension application file.
Background: Around 1750, Jost Kop was an original member of Ziegel's Church in Weisenberg Township, then Northampton County, now Lehigh County, Pennsylvania. Captain Henry Hagenbuch's company of associators, drawn mostly from Weisenberg Township, included "John Cup, Ludwick Cup, Andres Cupp, and George Cupp." This company fought at Long Island and Fort Washington and suffered greatly in British captivity. Andrew also went on to fight in the Philadelphia campaign of 1777. He apparently moved to New York later in life.
I have retyped the short extract from the pension application file as an MS Word document with annotations. If anyone would like me to attach it to an e-mail, just let me know.
