If you're thinking of using this crest because your name is Hogarth, please be advised that a legal entitlement is prerequisite and there are pitfalls and penalties for the unwise, or dishonest. Please visit The Baronage Press for an explanation of what actually constitutes 'entitlement'. A horse's head couped between two wings. Candor dat viribus alas. Under the listing of family mottos, it has 'Candor dat viribus alas'.
Candour gives wings to strength.
Boyd, Hogarth, Howgart, Rochfort. Howgart is a spelling of Hogarth that I've met only, so far, in the western border area and on both sides. The use of this form of the crest by a Howgart would be, I suspect, on the English side. I attach a picture. The Hogarth tartan is registered at Lyon Office in Edinburgh and can be seen at the Tartan Museum and also online here .
