It turned out that the buyer was in fact researching the surname Frearson (one name study) and didnt actually know any details about the Frearson from the postcard.
The surname Frearson is of early medieval English origin and probably derives from the word friar and would probably have been a nickname for someone who was pious and not necessarily a friar or monk.
Early Frearson's include Henry Frierson - marriage, 2 July 1571, London; and Agnes Frearson - marriage, 4 August 1577, Hawkshead, Lancashire.
