"… Joane (maiden name presumed to have been Phipps), having died in Plymouth, Jan. 7, 1660. A note by a person of reliability states: 'This Phipps is supposed to have been a sister of Constantine John Phipps (Baron Mulgrau), the great navigator and commissioner of the Admiralty. A younger brother, Viscount Normandy, was an officer of the British army.'"
7 January 1660 is more likely the date of her burial since that, and not deaths, is what was recorded in the parish registers of the period.
