Blomefield stated that Sir William Hoo was responsible for rebuilding the tower and nave of Mulbarton church during the later fourteenth century. His 18th-century description mentions that glass in a north window of the chancel showed, to one side, Sir Thomas de St Omer with his lady and (his daughter) Alice, kneeling, with the arms of St Omer and Malemayns: and, on the opposing side, Sir William Hoo and (his wife) Alice, beneath the arms of Malemayns and St Omer. The Hoo arms appeared at the top of the window, and below was a prayer in Norman French: "Priez pur lez almez Monsieur Thomas Sentomieris et Dame Perinelle sa femme qui fit faire ceste fenestre". Their daughter Dame Alice Hoo died in 1375 and she was buried at Mulbarton: the window therefore embodied the transition from St Omer to Hoo patronage. No recognizable parts of this survive among the fragments of medieval glass now re-set at Mulbarton.
