Brothers Lemuel and Darius Crosby

Here is a link to a transcript of the will of one Lemuel Crosby who names a brother Darius Crosby. Lemuel was a resident of Hillsdale, Columbia County, New York, when the will was written in 1807 but the will was proved in Dutchess County in 1809. J. Kelsey Jones speculated that Darius and Lemuel Crosby might have been sons of Isaac Crosby (1719-1815) and perhaps brothers of Elisha Crosby.
