Thomas Seyntaubyn, Esq. was Sheriff of Cornwall 37 Henry VIII. Thomas Seyntaubyn, Esq. was Sheriff of Cornwall 30 Elizabeth. John Seyntaubyn, Esq. was Sheriff of Cornwall 11 Charles I. John Seyntaubyn, Esq. was Sheriff of Cornwall 13 Charles II. who married Godolphin, and had issue John Seyntaubyn, Esq. (my very good friend) that married Anne, one of the coheirs of James Jenkyn, of Trekininge, Esq. who by letters patent, bearing date 11 March 24 Charles II. was created the 797th Baronet of England. He had issue by her, Sir John Seyntaubyn, Bart. that married De la Hay, and had by her issue another Sir John Seyntaubyn, now in possession of this place.
This famous worthy family, as it descended downwards, married Sergreaulx, Colshill, Whittington, Grenvill, Mallett, Godolphin, and others. The arms of Seyntaubyn are, Ermine, on a cross Gules five Bezants. And the said family was denominated from Mount Seyntaubyn in Normandy. Finally, as Sergreaulx’s heir, after the death of Sir Guy Seyntaubyn, passed away her lands from her issue by him to her children by her second husband, the Earl of Oxford aforesaid; so Jenkyn’s heir, after the death of Sir John Seyntaubyn, Bart. disinherited her heir by him, and sold most of her lands for the payment of her second husband’s debts, Mr. Spencer, of Lancashire; and after his death married one Mr. Page, for whose benefit she did her son Seyntaubyn what further damage she was able to perform by sale of more of her lands. So unconstant and irregular are some women’s affections.
Tregeare or Tregeire, Cornish Saxon, in this parish, id est, the dwelling of honour, or the honourable dwelling, gave name and original to a British family, from thence denominated De Tregeare. It is now in the possession of my very kind friend Richard Tregeare, Esq. Sheriff of Cornwall 3d of Queen Anne, and Receiver of the Land Tax temp. William III. who married Rawle, the relict of ――――, but died without issue, who left his estate to one of his name (though none of his tribe or blood, as I am informed), who gave for his arms, in a field Argent, a fess Gules, between three Cornish daws Proper.
For the name of this parish, it is in Cornish Crows-on, the cross; probably so called from some notable cross erected in the parish.
