One of my ancestors told his doctors about an aunt who suffered from 'bad epilepsy for 52 years'.
His Aunt Sarah was born in 1842/3 and did indeed die aged 52, having never married or left her parents' home - I've checked on FreeBMD and census. Her medical condition is mentioned only once, in the 1881 census, where her occupation (domestic servant) is crossed out and the last column states 'Imbecile, an epileptic from birth'.
Presumably some enumerator made the alteration. I don't think the family saw Sarah that way. Times have changed, thank goodness.
