The date of Charles Hoare's marriage to Joanna Hinksman is not known, but it must have been shortly after the expiration of his apprenticeship. Of their children three only are named in his father's will - Thomas, Margery and John; the other three mentioned in his own will - Daniel, Leonard and Joanna - being minors in 1632. There may have been others deceased, and probably of these were Ruth, buried June 1628, and Charles graduate at Oxford 1630, aged 17.
