Don’t fall for the Julian Calendar trip up


St Nicholas', Gloucester Parish Records are at County Record OfficeA friend of mine had this brick wall in their family tree.

They asked for my help and it was one that a moments consideration enabled me to break down for them.

We were looking at a family in the parish records of a small town in the south west of England. My friend had been examining records back as far as 1638 and had found an entry for a John Horn marrying an Joan Narbor in the parish church. The date was the 31st January 1638 and my friend said that this could not be her ancestor for the reason that John was still married to his first wife at this time.

I took a look and saw the baptism of a child, Edward son of John Horn, on the 26th August 1638 in the same church’s register as the marriage to Joan was recorded, followed sadly three days later by the burial of Ann, the first wife of John and mother of Edward on the 29th August 1638.

The answer was one that can trip up many family history researchers, when they are looking that far back, and is to do with mistaking the dates as recorded at the time in the Julian calendar and assuming it is recorded as we do today in the Gregorian calendar.

The simple solution is that January 1638 was in the last quarter of 1638 and came after August 1638 according to the Julian calendar.

The Gregorian reform started in 1582, in Pope Gregory XIII’s time, as in the image above but took some time to be adopted by Europe. It was 1752 that England and Wales adopted the Gregorian calendar a little later than some other countries, including Scotland. At that time 11 days were omitted – the day after 2nd September 1752 became the 14th September from the English calendar.

The first day of the year, or Supputation of the Year became the 1st of January, but only from 1752 in England and Wales.

Prior to this in England & Wales, the year began on Lady Day, or the 25th March. This would mean that in our example the 24th of March 1638 would be the last day of 1638 and the next day was the 25th of March 1639, and a new year.

The Calendar Act 1750 changed this situation, so that the day after 31 December 1751 was 1 January 1752. As a consequence, 1751 was a very short year – it ran only from 25 March to 31 December!

The year had previously been broken up into quarters, still in use for some legal practices, Lady Day (25th March), Midsummers Day (24th June), Michaelmas Day (29th September) and Christmas day 925th December).

To throw even more confusion into this situation, Scotland had already changed the first day of the year to 1 January in 1600 and so 1599 was a short year there ( remember that in 1600, Scotland was a completely separate kingdom). What has to be recognised is that when King James VI of Scotland also became King James I of England in 1603, the possibilities of date confusion must have been very large indeed.

 

So that brakes down that brick wall for my friend, as John Horn would have needed a wife to help bring up his children and so it is no surprise that he remarries quickly.
