Does that mean he is a womb twin survivor? There is a well-known connection between left-handedness and monozygotic ( identical) twinning and is possible that all left-handed people are womb twin survivors.
As for his stammer, there was more to this, in that he also had a slight speech defect over the letter R. You can listen to the original speech that he made before his speech therapy in 1938 on Pathe News.

Left handedness is said to be due to a later splitting of the original zygote, so that the split is into two mirrored halves rather than into two individuals. Conjoined twins often have mirrored organs, including having the heart on the wrong side.
There are many other left handers in the royal family today, including Prince Charles and Prince William.
My father Edmund Wigan worked with Dr Stephen Black, a neurologist, in the 1960s. Dr Black used hypnotic regression with his patients, and one man had a stammer. Dr Black regressed him to age 5 or so, when he began to speak normally. It was at this stage that he had been forced to write with his right hand rather than his left, which had been his preference until then. My father was most impressed by this and told us, - I have never forgotten. I haven't been able to find a link to a published article on this, but there is some anecdotal evidence - strange, I would have thought that some research would be very easy to do.
All in all, being forced to turn yourself into your lost right-handed mirror twin would be enough to upset anyone. It has been called "child abuse" to force left handed children to write right-handed.
A lot to think about here. We need more research. We now know how to identify womb twin survivors and we should be looking everywhere for signs and signals, such as stammering or forced right-handedness, - that may solve a lot of mysteries!
