Artane Castle was occupied by St.Lawrence (presumably by descent from this marriage) at the time of Silken Thomas' rebellion in 1534, when the Archbishop of Dublin, John Alen, enemy of the Geraldines, was captured there and executed by the rebels. See [Sweeney, 1991], [Archer, pre-1949].
Artane Castle is now gone, see [Bennett, 1991]. Artane Industrial School is on the site.
