Hi
There is a possible death for Henry registered in 1947 in Blackpool (Jan/Feb/March 1947 - 10b 663), the disaster being the previous March.
It only gives a birthdate of approximately 1899, but Henry's baptism is 5 March 1899 at St Bartholemew, Salford and that baptism gives a birthdate of 16 February 1899.
if he was injured, and if this is him, the death certificate may give a clue if he died some months after his injuries/of his injuries
There is a death for a Thomas in Fylde but its too early (1939) to be involved and the other one - Thomas Rawcliffe Singleton - is born in the wrong place.
