Thank you both 
Could it refer to something like epilepsy? She does go on to get married. albeit at the age of 37...(quite a dried up spnister really
)
The invalid was working previously as an ag lab, I suspect maybe some kind of farming accident happened to him.
Scrimnet...nice to see you
Have you heard anymore about becoming the Expert for WDYTYA?
Hello you!

He he he!!
I've just had to give the magazine "Best Of British" a telling off!!
They have a 1970s Oil Crisis Petrol Ration book in the April issue, purporting to be a WW2 one!!Talk about misleading...They also folded over a date stamp, so one could not see "1973" on it!!!
Not only the design gave it away, but also the Queen Elizabeth Crown all over it!!
Nothing from WDYTYA as yet, but wait out!!
As for epilepsy...that is a possibility...
Could be a farming accident, but all sorts of illnesses/conditions/etc were about at the time...
Married at 37...Not too unusual these days, but then...she must have been on the self for some reason...

Have you a death cert for her?? That may be interesting....
