The heir to extensive estates in Anglesey, Caernarvonshire and Cheshire, Bulkeley increased his family’s standing in Anglesey and was instrumental in obtaining a charter of incorporation for Beaumaris in 1562. At the 1570 musters his was the highest assessment in the island. He represented the county in Parliament on four occasions, and in 1571 he was a member of the committee on navigation (8 May).3Trans.

Although the family had profited from the dissolution of the monasteries, and a relative was the first protestant bishop of Bangor, a Catholic claim of 1574 that ‘all the Bulkeleys are Catholic’ is supported by Sir Richard’s connexions. One of his aunts was the last abbess of Godstow, and another married Sir William Norris of Speke. Bulkeley was taken ill early in 1572, and died 7 Sept. According to his heir he was poisoned by his second wife, whom the court of arches found had been committing adultery with one William Kenrick who ‘did use to walk under the said Agnes her window in the night time, play upon an instrument and make love to her when Sir Richard was from home in the Parliament’. Poison was found in a chest in her room, under a pair of velvet slippers, but a Beaumaris jury acquitted her of murder.4Cath. Rec. Soc. xiii. 109; D.
