About Joan Hawkins
Joan de Nash, an heiress, of Nash Court, married Andrew Hawkins near Fabersham, Kent, in the reign of Edward III. This is how the Hawkins became possessed of Nash court and from whom are descended the Hawkins of Devon. Joan is not the mother of John Hawkins but John Hawkins is a descended of Joan de Nash and Andrew. I am connecting them together since the reference connected them together this way.
