The Kierce Coat of Arms illustrated was drawn by an heraldic artist from information officially recorded in ancient heraldic archives.  Documentation for the Kierce Coat of Arms design can be found in Burke's General Armory.  Heraldic artist of old developed their own unique language to describe an individual Coat of Arms.

In their language, the Arms shield is as follows:
"Or, on a pile az, three galtraps of the field"

Translated as:
"Gold, on a blue triangle issuing from the top and pointing downward, not touching the bottom of the shield, three gold caltraps."

Above the shield and helmut is the crest which is described as:
"On a mount vert a tiger pass. ppr. collared and lined or, the dexter forepaw resting on a galtrap, as in the arms."

Translated as:
"On a green mound, a naturally colored tiger walking, collared and lined gold, the right forepaw resting on a caltrap, as in the arms."

Family mottos are believed to have originated as battle cries in medieval times.
The Motto recorded with the Kierce Coat of Arms is "RIEN SANS DIEU" (Nothing Without God)
