Meaning & History
The name Ason comes from Aythe where Aythe filius Thome received a charter of the lands of Fornochtis in Strathearn from Robert the Steward (later known as Robert II) around 1360. The next of the line was called Johem ayson iuuene. It can be seen how the surname Ayson is a derivative from "Aythe's son." The spelling and pronunciation changed over time, until it reached the modern form of Ason and its variants.
