I couldn't help but to post this article from Fayette County Texas in 1867. In LaGrange, the Yellow Fever outbreak caused 20 percent mortality rates with similar rates posted in Houston to New Orleans. We really have it better in comparison to our ancestors in the 19th century. I hope the link works.
