I have a special hobby horse among causes of death, which is moderpassion or modren or similar. It is often made into a synonym of hysteria, which I find totally inappropriate - a connection made by, I think, 19th century medicine between psychosomatic and mental disorders in women and the uterus.
What is recorded as moderpassion in the old church records will be any of the potentially lethal disorders of the female reproductive system that could affect a woman, apart from deaths directly related to child birth, for which there were other terms available.
Edit: Hans Högman does not list moderpassion at all (I think) but the FamilySearch list has moderpassion = hysterical fits.
