Of interest is John Schermrehorn - resident at Manlius in 1830 he is between 50/60 and with a large family. Recent clues - are: a dead letter at the post office in 1831 - to John G. Schermerhorn and another one for Dolly Schermerhorn. No other Schermerhorns are present. Any help with this John Schermerhorn and Dolly are most appreciated. Jack
