Hasculf de Tany

Hasculf de Tany (sometimes Harscoit or de Tani; It has been proposed that he was a close relative, perhaps even son, of Otuel fitzCount, whose father Hugh d'Avranches was viscount of that region, and that they were both related to the Suligny family, who were also from there. Because of his name, her earlier husband is often believed to be Edward of Salisbury the elder, an older man of the same name as her son.

Indications of a family connection to the Domesday Baron John fitzWaleran are implied by the grant, after his death, made by Hasculf de Tany's widow Matilda and son Graelan of the church of Fyfield in Essex to Bermondsey Priory. They also confirmed the gift of Roger the knight of John fitzWaleran who had given the tithes of Fyfield to that monastery.

Castellan in London In about 1115–1117, "Asciulus de Taneyo" was a witness together with Otuel fitzCount in a concord involving Gilbert, abbot of Westminster.

Also around 1130 Hasculf de Tany was a witness on London's first royal charter of liberties, granted by Henry I.

After Hasculf's death, the castellany of the Tower went to Geoffrey de Mandeville, the 1st Earl of Essex, and was held to be hereditary.

Death and legacy Hasculf was dead sometime between 1136/7, when he was involved in the legal case against Holy Trinity Priory, and 1141 when the empress Maud granted Geoffrey de Mandeville, the fief and serjeantry lands which Hasculf de Tani held in England on the day when he had died, which Graelan and his mother were then said to be holding. As noted by Stacy, the most recent editor of the 1166 baronial charters, the Tany barony, "with its caput at Aveley (Essex), comprised lands in Essex and Cambridgeshire" and its subordination under Mandeville by King Stephen and Empress Matilda "is unlikely to have survived the earl's revolt in 1143-4".

Graelen was succeeded by his son Hasculf and then his grandson Gilbert, who died in 1221 with no male heir. The barony was subsequently divided.

Hasculf also appears to have had a second son, Gilbert de Tanis, who was father to a younger Graelen in subsequent generations.
