Heraldry Sources?

[MacMillan of Rathdown]

These are the arms of Lord Kintore, Chief of Clan Keith, as drawn by Don Pottinger, Islay Herald, and one of the all-time greatest heraldic artists, ever. The drawing is copyright by his estate.

This is the clansman's badge of a member of Clan Keith, and may be worn by those who place their clan allegiance with the chief of that clan. As with the illustration above, it too is copyright by the estate of the late Don Pottinger.

When in the 18th century George Keith, Chief of the Clan, died without issue, his arms would have passed to either a brother, a nephew, or a cousin, and thence, by descent, to the present Chief of the Keiths, Lord Kintore.

I hope that answers your question.

Okay, I'm not trying to be difficult, I'm just trying to understand, does that mean that the Lord Kintore no longer uses their previous arms or do they now have two sets? Here is a link to what the original Earl of Kintore arms look like: http://www.clankeithusa.org/history-...ls-kintore.htm

Upon the death of George Keith in 1778 his entailed estates passed to Lord Falconer.

The arms seem to be Falconer quartered with Keith (I can't really tell because the illustration is too small for me to make it out properly). Since the Earldom of Kintore can pass through the female line it is likely that this occurred, thus promoting Lord Falconer from the rank of Baron to the rank of Earl and Chief of Clan Keith.

It is not especially uncommon for someone with a quartered coat to use only the pronominal quartering.
