All very interesting.
Watched the roadshow today, its obvious that the lady that was on the show didn't come from the Black Country when she found the 'treasure' when she was 12 year old in 1980.
The '39 register shows only 2 Bullsmoor Lanes, and 1 with the address 64 (unless there are some bullsmoor lanes on the Known missing places from Register e.g derbyshire and Kent etc), its likely the one in Enfield is the correct place as this has a garage as mentioned in the clues and Google maps shows this 'likely garage' as shown in the image I posted.
I don't think this was a scam/hoax or whatever and I think this actual treasure hunt took place on the 15th April 1940, but even with the info that were in the clues I think it will hard to find 'Catherine' as we haven't got access to all the relevant records, ideally we'd need rent/rate books for the house on April 1940 to find any Shorts living there as certainly on 29th September 1939 when the register took place no Shorts lived there. It seem improbable that by the 15th April 1940 (6 months after the registration) that the Fells had all moved out and the Shorts moved in but not impossible.
Let's all try and put this to rest (unless someone else has done this already) and get all the relevant facts together:-
15th April 1940 the date the clues were written
Catherine Short the name of the person writing the clues
1928 The Approx date of birth as mentioned by Catherine as she was 12 in 1940
64 Bullsmoor Lane the address in the clues
She had a Mother, Father, and 1 Older Brother (obviously all alive)
Her Mum had a sister, who was in a relationship with a man (may not be married)
She may have moved to the seaside between 16th April 1940 and 31st Dec 1940 (Cath says soon)
Does anyone else have any factual or logical information gained from the clues?
