Sir Thomas de Lathom of Lathom, Knight, son and heir, made settlement of Lathom, 49 Edward III, and died 6 Richard III (1382). From the Inquisition of 1383, it appears that he married Isabel, daughter of Roger de Pilkington; and from a later Inquisition of 6 and 8 March 1385, it appears that he married a second wife, Jane, daughter of Hugh Venables of Kinderton. The same Inquisition states that Sir Thomas was imbecile for three months before his death, on which event his widow Jane, then enceinte, sent his body for burial at Buscough Priory, without priest or other attendance and married her previous paramour, Roger Fazackerley, in conjuction with whom she claime dower on Wrightington, which was put to award in 7 Richard II.

The issue of Sir Thomas were Thomas, son and heir, Edward and Isabella, afterwards Lady Stanley, despite the Pedigrees of Herald's College which gives their mother's name as Jane Venables, most likely the children by Isabella de Pilkington.
