Patronymica Britannica (1860)

JASON. Albeit the baronet family of this name (extinct in 1788) bore in their arms " a golden fleece," I clo not think they ever proved their pedigree from the leader of the Argonautaa. It is far more probable that they were only Jamesons with the omission of a couple of letters.
