Hengar was formerly the seat of the Billings, alias Trelanders, whose daughter and heir was married to John Trelawny of Coldrinick, esq. by whom she had no issue; after his decease she was married to Dr. Lower, Physician in Ordinary to King Charles the Second, by whom he had three daughters, one married to Edward Morice of Werrington, esq. (by whom she had no issue); after his decease she was married to the honourable Major-General Charles Trelawny, governor of the Royal Citadel of Plymouth, now in possession of this place. Another daughter was married to Captain Mitchell; the third to ―――― Lower of St. Winnow. Pen-vos, alias Pen-vose. It is now the dwelling of Humphrey Nicoll, esq. Commissioner for the Peace, that married ―――― Cudworth. In this parish as I take it, or St. Kew, is still to be seen the ruins of a once famous and treble intrenchment of our ancestors the Britains, called Dameliock Castle, and taxed by the name of Dimelihoc, in the Domesday Book 1087, wherein Gothlois, (i. e. purple back or spear,) Earl of Cornwall immured or fortified himself against Uter Pendragon’s soldiers: in which place he was by them slain about the fifth century, as our annalists tell us (see Dundagell). Damelyock, alias Daimelack, as a monosyllable in British, Scotch, and Irish, signifies the hazard, skirmish, or battle house or place. The lands about this fort and castle, since its first erection, have been enclosed and cultivated, so that now it is comparatively defaced, but not so much as to obscure this treble ditch, camp, or intrenchment, from the sight of spectators or observators, or to obliterate its ancient name aforesaid; but query, whether this Dameliock Castle be not in St. Kew and St. Teath? Those Billings, alias Trelawders, mentioned on the other side, were gentlemen of blood and arms of three or four descents, and at Hengar, alias Hanger or St. Mabyn, married with the daughters of Blewet of Colon (who gave for their arms, Gules, a chevron between three eagles displayed Vert), Babb of Tingraze in Devon, Hockyn of Helland, and Helston in Cornwall, and gave for their own arms, in a field Or, on a bend Sable three stag’s or buck’s heads couped at the neck Or, attired and armed of the Field. The which Billing, heir of St. Mabin, was married to Hamley of Treblethick 1630. Note further, that Tredinick of St. Breock gave the same arms as Billing or Trelawder of Hengar, only differenced with the colour of the stag’s or buck’s heads, viz. in a field Or, on a bend Sable, three buck’s heads attired or armed Argent. TONKIN. St Tudy, in the hundred of Trigg, hath to the northwest St. Kew, to the north that and St. Teath, to the east Michaelstow and Brewer, to the south St. Mabin. In anno 1291, 20 Edward I. this church by the name of St Tudy, was valued (Tax. Ben.) at c_s._ having never been appropriated.
