A very interesting piece Varche.
The snow of 1822/23 I believe was quite typical of the whole country at the time, but it didn't always lead to such loss of life. However, the freezing over of rivers, like the Thames, was quite regular, and that is why Charles Dickens stories often feature a vision of much snow, much ice,and the poor freezing cold in over crowded houses when the UK suffered a mini ice age, that had also occurred in the 16th century, let alone the big Ice Age that started to end about 11,000 years ago.
1947 is obviously within living memory, although not in mine! Mum and dad used to talk about it, and the fact, as I have studied, that it was made even worse by the coal and food shortages of the post war period when the country was bankrupt. The next big freeze was the one of 1962/63 (It started down South on Boxing Day), but I didn't see it as I was nice and warm in Malta GC!
Memories, and historical reports like the one you have found Varche are just so valuable in the facts they provide in a secondary form, but sadly
of course we have lost the primary source of this information a long time ago.
