Crisane, you are a star. Many thanks.
Yes, Ann Cassell was deaf and dumb, as was her mother who amazingly managed to rear to adulthood and marriage, some 12 children. Ann is the last one that I have found as an adult.
Unfortunately, the problem which caused the deafness (and therefore dumbness) has passed right down through the generations to several of my kin, and my grandson.
Comparatively easily remedied nowadays. Called glue-ear.
Thanks for your help.
