No conclusive evidence of Tretherf’s parentage has been discovered, but it is highly likely that he was in some way related to John Tretherf*, one of the Cornish knights of the shire in 1437, when Gregrory himself represented Truro. His lands, if any, were evidently insubstantial, for he was not included among the individuals drawing an income of 40s. or more subject to the income tax of 1451, even though it is possible that, like his more prominent kinsman Reynold Tretherf, he refused to meet the tax assessors.
