We have already mentioned that the property of the de Lacys (including, probably, Kirkby) passed to Thomas, Earl of Lancaster, who was afterwards beheaded for rebellion, being led out for execution by an officer named Gasgoyne. It would appear, therefore, that a Gasgoyne held some official post at Pontefract Castle, and that Lordship (as we have seen), was connected with Kirkby, as belonging to the same noble owners, de Lacys, and others; and hence the Gasgoyne arms appear along with those of the de Lacys, and others. The name of Gasgoyne is found in Stow’s copy of the roll of Battle Abbey, as among the distinguished soldiers who came over with the Conqueror, coupled with Gaunt, Gaunville, and many another good name. At the dissolution of religious houses by Henry VIII., we find among institutions to benefices, that Robert Brantingham, was presented to Kirkby, in 1565, by Robert Brantingham, of Horncastle, by reason of the advowson, for that turn, being granted to him by “the late Prior and Convent of the Cathedral Church of Durham.” And so ended the connection of Kirkby with the See of the proud Bishops of Durham. On the extinction of the Cromwell line these lands, in Tattershall, Tattershall Thorpe, Kirkby, &c., would revert to the King. Henry VIII. granted Tattershall, and doubtless the other possessions, to his mother Margaret, Countess of Richmond; and in the following year entailed them on the Duke. On the latter dying without issue, Henry granted a vast number of estates in this, and other localities, to Charles Brandon, Duke of Suffolk. On the death of two infant sons of the Duke, shortly after their father’s decease, Edward VI. granted them to Edward, Lord Clinton, whose arms were also among those formerly in the rectory windows. His descendant Edward Earl of Lincoln, died without issue in 1692, when the properties passed to his cousin Bridget, who married Hugh Fortescue, Esq.; whose son was created Baron Fortescue, and Earl of Lincoln in 1740; and a large portion of Kirkby is still the property of Lord Fortescue, who is Lord of the Manor, other owners being the Clinton, Wilson, Ashton, Lely families, Lockwood trustees, &c.
