Manor of Hooks and Pinnacles
"In 1449 William Say, clerk, John Say and Lawrence Cheyne his [father]-in-law (fn. 233) were listed as tenants of a group of manors including Hooks.

Wikipedia says his father was Thomas Howard, 2nd Duke of Norfolk, not John Howard (as listed in this profile). I didn't see an existing John Howard 1443 – 21 May 1524 to connect as father. Do we have to create a new one? See http://en.wikipedia.org/wiki/Thomas_Howard,_3rd_Duke_of_Norfolk. The picture here is actually Thomas Howard II, so it looks like father and sone were accidentally merged.
