Parents and sons worthy each other, whom love made one in life, one distemper in death and one grave in burial. Each of them was embellished with useful learning, which their modesty seemed to conceal, and in their youth the man grew up with them. They were born for their country and to honours, which the eldest, being Captain in the army, acquired by his fatigues over all England. William died April 17, 1680 aged 20.
