Caudle History, Family Crest & Coats of Arms
An ancient Strathclyde-Briton family from the Scottish/English Borderlands were the first to use the name Caudle. They lived in Renfrrewshire. This place-name may also be derived from the Old English words caeld, which means cold, and welle, which means well, and indicates that the original bearer lived near a well that gave cold water.
Early Origins of the Caudle family
The surname Caudle was first found in Renfrewshire (Gaelic: Siorrachd Rinn Friù), a historic county of Scotland, today encompassing the Council Areas of Renfrew, East Renfrewshire, and Iverclyde, in the Strathclyde region of southwestern Scotland, at the Caldwell Tower, a mansion and old estate that dates back to 1294.
The current Caldwell Tower stands on a mound, and is a small, free-standing tower that was probably built in the 16th century.
It was fully restored in 2011 with the addition of a small extension. Caldwell is also a village and civil parish in the Richmondshire district of North Yorkshire.
"The old family of the name appears to have ended in the direct line in an heiress in the fifteenth century. In 1342 there is an entry of the fee of William de Caldwell. Robert Cauldwell was a merchant in the service of Sir John of Montgomery, 1405." 
The Caudle variant may be related to a thickened and sweetened alcoholic hot drink so named. It was popular in the Middle Ages for its supposed medicinal properties and dates back to at least 1297.
Further to the south in the English county of Yorkshire, the Yorkshire Poll Tax Rolls of 1379 listed: Johannes de Coldwell; and Thomas de Coldwele.

For Scottish immigrants, the great expense of travel to North America did not seem such a problem in those unstable times. Acres of land awaited them and many got the chance to fight for their freedom in the American War of Independence. These Scots and their ancestors went on to play important roles in the forging of the great nations of the United States and Canada. Among them:
Caudle Settlers in United States in the 19th Century
Caudle Settlers in United States in the 20th Century
Emigration to Australia followed the First Fleets of convicts, tradespeople and early settlers. Early immigrants include:

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Fac et spera
Motto Translation: Do and hope.
