Before we mock the name Throckmorton, we should understand that the surname Throckmorton was first found in Worcestershire at Throckmorton, a chapelry, in the parish of Fladbury, union of Pershore, Middle division of the hundred of Oswaldslow "where John de Trockemerton, the supposed ancestor of this family, was living about the year 1200. From this John descended, after many generations, another 'John Throkmerton,' who was according to Leland, 'the first settler up of his name to any worship in Throckmerton village."
Some of the family held estates at Weston-Underwood in Buckinghamshire in early times. " In the parish is an ancient [family] seat, now uninhabited, of the Throckmorton family, who have also a neat Roman Catholic chapel here, with a handsome residence for the priest."
With that understanding, I think we can agree "Throckmorton" is not so funny.
