John Aylmer was an English churchman who became Bishop of London in 1577. He was a Protestant cleric and writer and acquired Suffolk property, including Akenham and Claydon, with or for the benefit of his son Samuel.

The Akenham purchase is recorded as occurring in 1586 in the manor history; the legal-history account dates the broader Aylmer acquisition to the 1580s.
