Church of St Laurence, Upminster Church of St Laurence, Upminster The church of St Laurence, Upminster, is the Church of England parish church in Upminster, England. It is a Grade I listed building. It is the historic minster or church from which Upminster derives its name, meaning 'upper church', probably signifying 'church on higher ground'. The place-name is first attested as 'Upmynster' in 1062, and appears as 'Upmunstra' in the Domesday Book of 1086. Alice Perrers, mistress of King Edward III, was buried in the church or churchyard in 1400. There is no memorial to mark her grave. She had three illegitimate children by the
English and British royal mistress who had also been courted by Edward's brother and an Austrian prince, Daisy Greville, Countess of Warwick, Agnes Keyser, and Alice Keppel, who of all his mistresses had the most political power and sat at his deathbed in 1910. He fathered surprisingly few royal bastards considering their number and the fecundity he enjoyed with his wife Alexandra of Denmark. Edward VIII is the only member of the currently reigning House of Windsor to have kept a mistress. Among them were mostly married women like Freda Dudley Ward and Lady Thelma Furness. He first met Wallis Simpson in San Diego, California
