While the antecedents of the Hores of Cambridgeshire are unclear, it is possible that Gilbert’s father came from the Hore family of Elmdon in Warwickshire. John Hore made his way in the world by serving in the household of Richard II, and he greatly enhanced his standing as a landowner through his three marriages. Gilbert was John’s son by his first wife, through her mother the coheir of extensive estates spread over several counties.
In 1430 or early 1431 Gilbert went to France on the young Henry VI’s coronation expedition. He crossed the Channel as a member of the retinue of Sir John Baskerville, but there is no evidence to explain how he developed an association with that Herefordshire knight. His name afterwards appeared in a couple of petitions presented to Parliament by the duke of York, the earl of Warwick and others who had taken part in this enterprise. The petitioners sought their wages for a period of ten months beginning in March 1431 and suggested that they should receive them from the revenues of the late duke of Bedford’s estates, indicating that they drew up the petitions after Bedford’s death in September 1435.
If Gilbert did not return to England with the King in January 1432, he had probably done so before his father’s death in or around 1434. John Hore appointed him his executor, in which capacity the younger man received a royal pardon in 1437.
Shortly afterwards, Hore gained election to his only Parliament. If he had received any external support when standing for the Commons, it may have come from the Crown, for it is possible that he was already an esquire of the Household, which he had certainly joined by 1438-9. As such, he received 40s. p.a. in fees and robes, and he remained a member of the Household for the rest of his life.
The most dramatic episode of Hore’s term as sheriff was Cambridgeshire’s disputed parliamentary election of 1439. In Cambridgeshire, the election of the knights of the shire became the focus of a struggle for hegemony between Sir James Butler (later earl of Wiltshire and Ormond), a newcomer trying to assert himself locally, and the dominant magnate in the shire, Lord Tiptoft. The parliament roll shows that, on 16 Nov., four days after Parliament had opened at Westminster, the King and Lords ordered a new election in the county because, for ‘certain reasons’, Hore had not returned two knights for that shire. While the roll does not specify those reasons, it appears that Hore’s justification for abandoning the original election was the presence of men not eligible to vote and the riotous behaviour of those supporting Butler’s candidates. In reality, he had aborted it at Tiptoft’s behest, although some sort of disturbance must have occurred, since the writ for the fresh election ordered that none who was armed or not statutorily entitled to attend should take part. In the end, Tiptoft’s interference failed, for at the second election on 19 Nov., presumably held by Henry Langley, Hore’s successor as sheriff, two of Butler’s allies, William Allington II* and William Cotton*, were elected.
The association with Tiptoft did not prevent that peer from suing Hore for debt in early 1442, although the action appears never to have progressed to pleadings.
In the following year, Hore obtained another royal pardon, as of Great Childerley.
