Murphy was buried there (Fultonham) next to his first wife. In 1872, he was reinterred at Middleburgh cemetery. Although the State Legislature voted to erect monument to Murphy in 1819, none was built until some of his descendants purchased one to be placed in the cemetery in 1910. In 1913, the Ancient Order of Hibernians placed a marker commemorating Murphy at the Saratoga Battlefield, and the state put up its own marker there in 1929.
The three that intercepted Major Andre got lucky, and their motivations for their blockade has come into question (perhaps to rob persons?) At any rate, they were all local folks from an area about 100 miles from Schoharie County.
Your trip sounds like a good one...
No RevWar this year - well, maybe close. Supposed to see some F&I fort in west PA this year. ;-)
