More may be added to the earlier biography.
While up at Westminster for the first recorded time as a Member of the Commons, Squibbe acted as an attorney in the court of common pleas for a man from his home town of Shaftesbury.
A lawsuit of 1438 reveals that Squibbe also received an income from sheep-farming. He accused a husbandman and a shepherd of breaking his closes at ‘Asshemere’ in Dorset, and attacking 40 of his ewes with their dogs, so that 20 died and 20 aborted. He claimed that each ewe was worth £2, and valued the crops taken at the same time at £5.
