She married John Barnard, as his third wife, on 2 Jan 1567/9.
World Family Tree lists the following children, which lines up with the marriage record (unreliable source):
Richard Vicar Barnard b: 11 APR 1568 in Epworth, Lincolnshire, England
Francis Barnard b: 5 JAN 1570 in Epworth, Lncs Co., Engl
Joan Barnard b: 1575 in Epworth, Lncs Co., Engl
Margaret Barnard b: SEP 1585 in Epworth, Lncs Co., Engl
That would make her birth date about 1546 rather than 1520, however, her listed parents would then be too old. Perhaps a generation was skipped in the online genealogies?
