Does anyone know when, between 1900 & 1910, Maggie Adkins Calvert died? She was married to James M. Calvert, who was a son of Harvey P. & Mary Mitchell Calvert.

James & Maggie were living in the Callands District of Pittsylvania County, Virginia on the 1900 census. James was widowed by the 1910 census.

I'd like to narrow down her death beyond a ten year time span. Thanks to anyone who can help.
