For a given value of fun of course. The register of all the people in the country in 1939, the pre-war census thingammiebob.
So, looking up my name (Worstall, obviously, because it’s rare and easier to look up than mother’s maiden name) I see Great Aunt, Uncle, no idea who the bloke in Pewsey is, Grandmother and that’s it.
Father and Grandfather don’t seem to be on it. Which is a bit odd, as father’s address at the time was the same as Grandmother’s and Uncle’s (he wouldn’t have been away at school at that time, too young) and Grandfather was career RAF so they should have known where he was (at the same address I think….some airbase in the Cotswolds, Calne maybe? Although that’s Wiltshire I think. Summat like that anyway).
The other grandfather, mother etc don’t seem to be in there at all.
So, not hugely accurate I would say.
