[1] The family name, ultimately derived from Folleville in the French region of Picardy, is attached to several other sites in Leicestershire, such as the deserted village of Newbolt Folville.

[1] Folville was summoned with horses and arms to a Military Council before the King's teenage son and Lieutenant of England held at Rochester, Kent in September 1297, a few days before the English defeat at the Battle of Stirling Bridge.

[7][non-primary source needed] King Edward soon returned from his expedition to Flanders and took charge of matters in Scotland and gained revenge at the Battle of Falkirk the next summer.

[10] In 1304 he was accused of breaking into the home of William Hubert of Teigh and carrying away charters and muniments[11][non-primary source needed] but appears to have been excused as in 1306 he was appointed as a commissioner to enquire into progress on the building of a prison in Leicester.

[13][non-primary source needed] Folville's wife Alice outlived him but found herself in trouble when she was imprisoned in Lincoln prison in September 1332, perhaps in relation to some of her sons' activities.
