February, 1807, he married Hannah Hoes, a distant kinswoman. In the
winter of 1806-7 removed to Hudson, the county seat of Columbia County,
and in the same year was admitted to practice in the supreme court.
In 1807 supported Daniel D. Tompkins for governor against Morgan Lewis,
the latter having come to be considered less true than the former to
the measures of Jefferson. In 1808 became surrogate of Columbia County,
displacing his halt-brother and partner, who belonged to the defeated
faction. In 1813, on a change of party predominance at Albany, his

and became thereby a member of the court of errors, then composed of
