Background
He was born at Scaleby Castle, Cumberland, son of Sir Robert de Tilliol (died 1320) and Maud de Lascelles.
He was born at Scaleby Castle, Cumberland, son of Sir Robert de Tilliol (died 1320) and Maud de Lascelles.
The Tilliol family had been granted Scaleby by Henry I and over the centuries had become one of the leading landowning families in Cumberland. In 1322 Tilliol was on the Scottish border with Andrew Harclay, 1st Earl of Carlisle. This might well have been politically dangerous since Carlisle"s decision to make a truce with the Scots led to his downfall and execution for treason in 1323.
Tilliol however seems to have escaped unscathed.
He was twice High Sheriff of Cumberland in 1327 and 1329, and represented Cumberland as knight of the shire in the House of Commons of England. He sat regularly as a Commissioner for oyer and terminer, and in 1341 he was given a special commission by Parliament to punish rebels and suppress trespasses in Cumberland.
Tilliol may have been a compromise candidate. He went to Ireland in the spring of 1331 but returned to England almost at once.
The male Tilliol line died out in 1435.
