Apologies if I've posted this before on a different thread.
I have researched OH's family quite thoroughly, with the help of his 90 year old uncle.
One old photo showed OH's grandfather in an admin-type role in WW1, signed by grandfather himself - & dated Nov 1915. (Once again thanks to the experts on the Armed Forces board and Cambridgeshire Reg historians who helped me with that).
Now this man was shot in the head on the Somme in April 1915 & sent to England for treatment.
So obviously his treatment and recovery were successful and by the end of the same year he was already back in uniform, albeit in a training battalion.
I explained all the (to me) fascinating background to the 90 year-old. (The man's son). His reply was "no that can't be right, he had to spend the rest of the war learning how to walk and talk again. That's what we were told. Your information must be wrong".
I realised he had been brought up to consider his father something of a hero and his recovery miraculous. I just stopped discussing it with him. I have all the facts, OH knows it all, why would I want to unnecessarily cause distress to a man of that age?
Conversely he is absolutely convinced his parents had to get married as his sister was on the way......in vain I have shown him the evidence of his parents' marriage, well before his sister's birth, he won't believe it.
