I apologise if this has appeared twice but after posting it the first time it didn't appear.

I am looking for a good source of information which will give me the history of why people died - mainly - from TB. My g/parents both died within three months of each other leaving seven children, in late 1908 and early 1909 from TB, I have the death certs to verify this. I suspect it was mainly from the living conditions but would like some details.

Many thanks
