?BE1883 (Burgh of Kent) reports that William was father of both Adelme (described as ancestor of the house of Clanricarde and numerous families of De Burgh, Burgh, Burke, etc) and John and reports that that John was father of Hubert, Earl of Kent. BE1883 (De Burgh of Ulster) reports that Richard de Burgh 'the Great' was son of William FitzAdelm. Various web sites therefore show Richard 'the Great' as son of William son of Adelm son of William of Cornwall. HOWEVER:
(a) TCP (Cornwall) reports that William of Cornwall probably died without issue so this connection is probably not secure.
(b) TCP (Ulster) calls the suggestion that William de Burgh, father of Richard' the Great', was the same person as William FitzAdelm as an "extraordinary belief" that has been "exploded". It says that William de Burgh's parentage is unknown.
(c) TCP (Ulster) reports that William, Lord of Connaught, was brother (probably the elder brother) of Hubert, Earl of Kent. This compares with the implication by BE1883 that they were cousins.
(d) TCP (Kent) says that Hubert of Kent's parentage is unknown although it does report some unproven suggestions.
We follow TCP but add input from BE1883 that provides the above connection with William of Cornwall and identifies Hubert's father as: John de Burgh.?
