Burke’s Landed Gentry of 1871, p. 1120, says that he “s. his cousin, Edward Arblaster, in the property of Westwood, co Stafford”

His aunt Bridget Powys had married an Edward Arblaster in 1729 and they had a sole child, another Edward, so it sounds as if the younger Edward Arblaster died without children leaving a property to his first cousin.
