In 1527-8 he obtained "letters of fraternity" from the Abbot of Westminster, and in a volume of MS. pedigrees at Tabley, near Knutsford, there is still preserved the original grant under the convent seal of the abbey, dated January 5th, under which John, abbot of that house, grants to Sir John Stanley and dame Margaret, his wife; John Stanley, their heir; and Anne Stanley, their sister; that they shall be prayed for in that monastery, "_in vita pariter et in morte_," and all other places in their order through England, and that their names shall be enrolled on the fraternity's martyrology _post obitum_. Whatever may have been the cause of Sir John's withdrawal from society, certain it is that, having arranged all his worldly affairs, he and his wife, in 1528, prayed for a divorce in order that they might severally devote themselves to a religious life and be quit of the world. The divorce was granted, Sir John and his wife were released from their marriage vows, and put asunder one from the other for ever. He entered the Abbey of Westminster, and assumed the cowl and tonsure of a monk, and it is believed that his death occurred shortly afterwards. Mr. William Beamont, in his "Notes on the Lancashire Stanleys," thus sums up his character:--"His mind turned towards seriousness if not sadness. He loved the Preacher's motto 'All is vanity,' and where he could he liked to inscribe it openly. This natural tendency was deepened and increased by the stigma of his birth and other circumstances which he could not forget. The stain on his father's life, and his death excommunicated, would not let him, even in the inscription on his grave, where he supplicates for him the prayers of the faithful, call the bishop by the sacred name of father, and in the letters of fraternity all mention of his father's name is avoided. Sir John's mind dwelt too much upon chantries, burial-places, obits, indulgences, and the like. It was his favourite subject, and he crowned this part of his career by retreating from the world and disappearing in the deep shadow of the cloister." Sir John left an only son, bearing his own baptismal name, who was an infant at the time of his parents' divorce. His father's will provided that he should be placed under the care of the Abbess of Barkyng until he should attain the age of twelve years, when he was to be transferred to the care of the Abbot of Westminster, with whom it was directed he should remain until he was twenty-one, when, and not before, he was to be at liberty to choose himself a wife, with the advice of the Abbot of Westminster and Edmund Trafford, Esq. Of his subsequent career little is known. He attained to manhood, when he married Ellen, daughter of Sir Edward Fitton, of Gawsworth, Knight, but does not appear to have had any issue by her. He was living in 1551, but after that all trace of him is lost, and with him the line terminated.
