John Leigh was the son of Nicholas Leigh and the builder of the sixteenth-century Addington Place traditionally dated to 1544. He died in 1576 and was buried at Addington.

The public account gives the family succession but not a separate surviving deed for John's acquisition.

The chronology of the mansion's construction varies in secondary accounts; the manor connection is the relevant evidence here.
