Notes for Isaac Hollenbeck: Isaac Haulenbeck was a resident of the town of Danube (then including present-day Stark) in 1820, and in 1835 he was listed in Stark. (There was a Nathaniel Hollenbeck in the Canajoharie district in 1790, but there were no children listed in his family at a time when Isaac would have been about two years old.)
Isaac and Polly were in Stard in 1850 but had vanished by 1855 (perhaps then dead).
