In 1836, Joseph bought his son, Junius, a partnership in the Hartford dry-goods house of Howe and Mather. That same year, Junius married Juliet Pierpont, daughter of the Reverend John Pierpont of Boston, pastor of the Old Hollis Street Church. This union of Morgan and Pierpont joined together in their infant son, John Pierpont, born in 1837, a wildly improbable set of genes.
