Hi,
My earlier response was oversimplified - my apologies.
A Find My Past search based on John Bateman born in 1880 does not appear to pick up the existence of John in Wolverhampton in 1911. A search based on Hettie Bateman is more productive. In the 1911 census household transcription, his wife Hettie was recorded as the head of the family but there is still no mention of John. However, the original census image does indeed show that John was alive but not at the family home. He was still a baker but now termed as a worker rather than as an employer. I have taken this to mean that the family business no longer existed.
I am curious as to whether this family tale about the bakery accident, presumably prior to 1911, has any factual basis as it may go some way to explaining why John was no longer an employer in the bakery trade. I have started to research inquest records on the internet for that period but so far nothing has come up.
