Maybe it was while all the churches in Stamford were ringing their bells backwards to summon Royalist support that Francis was doing her bit to save the town from an attack?
Francis Wingfield was the daughter of Edward Cromwell, 3rd Baron Cromwell of Oakham in Leicestershire and the great great granddaughter of Thomas Cromwell. Thomas, as you will know, was chief minister to King Henry VIII, his sister Catherine William was the great grandmother of Oliver.
You may be wondering why Oliver had the surname of Cromwell when the family's surname was William? Catherine's husband was Morgan ap William, but their family had abandoned the Welsh naming system of 'ap or son of' in favour of the English use of a surname and therefore their descendants took the name of Cromwell.
