Clement • Link
aka "Jack" per L&M companion. Previously apprenticed to his father, John, a tailor and woollen-draper in Cambridge.
Father John was--I think, following imprecise pronouns--brother to Percival Angier, who "married Elizabeth Pepys, (daughter to Thomas 'the Red', Pepys's great uncle) at St. Sepulchre's, Cambridge, in 1633. He became a prosperous London business man, with investments in Irish land and E. India stock."
