Above are two renderings of the Bisset/t Coat of Arms. The one on the left has been kicking around for over 50 years, that I'm aware of. It was included in the Historiography above. I've only recently seen the coat of arms on the right. It came from House of Names. The one on the right has been slightly colored. The one on the left could be colored if someone knew the correct color scheme. (...as of 2009)
Each of them has been drawn from Heraldic information found in Burke's General Armory archives. Heraldic artists would develop their own unique language to describe an individual coat of arms, so unless you saw an original, there could be hundreds of interpretations. The original description went like this...
"Az. on a bend within a bordure crenellee
ar. a mascle gu. in the dexter chief
a nartlet of the second."
When translated, the arms description goes something like this...
"Blue on a silver diagonal band,
within a silver crenellee border,
a red diamond pierced,
in the left top a silver bird without feet."
Depending on punctuation, you could read that a couple ways. Read it over again and you'll see what I mean. Above the shield and helmet is the crest, which is described as...
"The stump of a tree ppr"
That translates into...
"The stump of a tree in natural color"
The motto recorded with the coat of arms in Burkes General Armory is...
If we were all given that description and asked to come up with a rendering, we would all have different drawings, to be sure. However, leaving color out of the equation, the rendering from the House of names neglects several items. The most glaring omissions are first, the bird - and second, the red diamond with a hole in the center. I've never been able to figure out what the diamond could represent, especially having a hole in it.
Anyway, I hope you found this as interesting as I did.
