I'd look for Sabre's death in Lauderdale co. MS. I'd contact the genealogical and historical societies and ask if they have a local death index, indexed newspaper death notices and cemetery inventories.
On the 1900 Meridian Census Charlott with her mother is listed as a widow but she wasn't. Her husband Thos. and children were also living in Meridian.
