Nothing is known for certain about Somaster’s origins, but he owned property both in the city of Exeter and at Halberton, and by the early sixteenth century his family also had holdings in the Totnes area, in Barnstaple and elsewhere in Devon.
While he never held Crown office, Somaster did serve successive sheriffs of Devon as an under sheriff or other official, and in this capacity he was regularly entertained with food and wine by the Exeter authorities.
Increasingly, Somaster found himself in a position to command lucrative legal fees. He could now consider himself a lawyer of some note, for by the early 1440s he found employment among the greatest members of his profession, including the famous Nicholas Radford* and the later chief justice, John Fortescue*, who had served as a governor of Lincoln’s Inn alongside him.
