RESEARCH NOTE:
    Mary Lewis was the daughter of William Lewis and Margaret Banaster. She married, firstly, William Jephson before 1691. She married, secondly, Sir John Aubrey, 2nd Bt., son of Sir John Aubrey, 1st Bt. and Mary South, after 1691. She married, thirdly, Sir Charles Kemeys, 3rd Bt. in 1701. She married, fourthly, William Aubrey, son of unknown Aubrey, on 10 August 1703 at Boarstall, Buckinghamshire, England. She died in 1717, without issue. She was buried at Boarstall, Buckinghamshire, England.

RESEARCH NOTE:
    Peerages both say that she died withouth issue and that she had a daughter Frances Jephson.  It must be that the peerages mean that she died without MALE issue, a matter of concern for nobility.
