that’s my basic question. i know it’s broad with several possible givens. let’s first assume my actual case. my two aunts on my father’s side are deaf-mutes (four sibblings and our late father was the only boy.) as kids we were aware of this and our parents’ fears which they sometimes let slip. things got a little edgier as we grew to adolescence and started dating.
our sister, something of a real-life hermione granger, did some research while still a child. she discovered that in our father’s generation, only his two sisters had this condition. old timers cannot remember a case before our aunts’, nor have there been any abnormalities in our generation, even with cousins who married early and had kids. our sister also learned that before and during WWII when she mothered our aunts, our grandmother was often sickly. it could have been an illness, poison or some kind of infection. the clan lived deep in the farm belt. no likelihood of poisoning there.
happy to report my 8-year old daughter is as healthy and normal as one could wish for, as with all my nephews and neices.
