I'm really not sure about Hannah, but Robert W. Murdock died on October 19, 1910.
According to the 1910 US census, he was living with his daughter Mary Raines (who by that time was a widow with five children living at home) in Ettowah County Alabama. So I assume that's where he died.
Sometime after 1920, the children of Mary (Murdock) Raines moved to the Wayne County, Mississippi area. I can't find any records on Mary after the 1920 census, so I assume she died before 1930 in AL or MS, but I'm not really sure.
Do you still keep in contact with any of the Murdock family? I'd be interested in finding out where they ended up, as the Raines family lost touch with them when my grandfather was still a child (he's 86 now), and he only remembers the name, not much else.
