I'll keep my eyes open for anything about the Cousins. Somewhere we have photo's of Smith, Hannah, Dorothy and Muriel if they're of any interest to you, I think my sister who is now the matriarch of the family has them.
I know Smith Cousin was a teacher, and he taught for a while in the Oxford area I think, both daughters were teachers as well, and the family have a plot in Oakworth Crematorium Graveyard.
