The 1921 census became available on Find My Past a few weeks ago. We'll find some interesting things! This period is almost in living memory as in we can remember what parents and grandparents said about it. I'm going to delay looking for a little while because I've read of a few transcription errors and, being a pensioner now, don't fancy paying £x per search if the info is going to be wrong when I get the result.
Some of the other genealogists in the family on our My Heritage site have already started looking so you may see some info carried over to our tree soon.
