Esther Susanna Flickinger

Esther Arnold Flickinger was supposed to be the niece of Benedict Arnold, but the following implies that the relationship must've been more distant:

Wikipedia: Benedict was born the second of six children to Benedict Arnold (1683–1761) and Hannah Waterman King in Norwich, Connecticut, on January 14, 1741.[1] Like his father and grandfather, as well as an older brother who died in infancy, he was named after his great-grandfather Benedict Arnold, an early governor of the Colony of Rhode Island.[1] Only Benedict and his sister Hannah survived to adulthood; his other siblings succumbed to yellow fever in childhood.[6] His siblings were, in order of birth: Benedict (August 15, 1738 – April 30, 1739), Hannah (December 9, 1742 – August 11, 1803), Mary (June 4, 1745 – September 10, 1753), Absolom (April 4, 1747 – July 22, 1750) and Elizabeth (November 19, 1749 – September 29, 1755). Through his maternal grandmother, Arnold was a descendant of John Lothropp, an ancestor of at least six U.S. presidents.[7]
