My research has shown Jonathan Wilburn Wright (1844-1914) had 3 children die in 1880. Mary (1874-1880) Rebecca Jane (1877-1880), Malinda (1879-1880). They died after the census enumerator was at their house in June, 1880. The Kentucky Death Record Database does not have Morgan County in 1880. Does anyone know if this information is correct? If so, how did they die?
