*NOTE ON CALENDAR: England continued to use the Julian calendar up to 1752 whereas the Gregorian ('New Style') calendar had been adopted on the Continent in 1582.  Scotland changed the beginning of the year from March 25 to January 1 in 1600, but did not adopt the Gregorian calendar until 1752 at the same time as England.  By 1751 the Julian calendar was 11 days out of step. In that year Chesterfield's Act stated that 1 January should be the first day of the year (previously the year commenced on 25 March). Thus 1750 had commenced on 25 March 1750 and ended 24 March 1750/1. 1751 commenced 25 March 1751 and ended on 31 December 1751. 1752 commenced 1 January 1752 and ended 31 December 1752.  However, 11 days of September were omitted to bring it into line with the Gregorian calendar. So the convention in expressing dates that occurred in the period from 1 January to 24 March in the years before 1752 is to first show the year that would be shown on the record (according to the Julian calendar), then show the year it would have been if expressed according to our present calendar (Gregorian). Jonas' burial is shown as 1661/2 to reflect the two calendars: '1661' (Julian calendar) and '1662' (Gregorian calendar).  For more details on the calendar change and differences click here.
