On December 25th, 1930 my mum's brother married my dad's sister (so a brother and sister married a brother and sister) and they had a "double wedding" on Christmas Day, in Southwark Cathedral.

One of my mum's other brothers got married on the same day in Southwark Cathedral too, so I guess my grandma had a busy day that day, to say the least (three of her children getting married within an hour or so).

How unique is this?
