Lanier/Groves Family

I am trying to locate information on the death of Belle Groves Lanier, my great-great grandmother.  She lived in Mason County and Kanawha County, West Virginia.  She was married to Benjamin Oscar Lanier in 1895.  In 1914 Benjamin Oscar "Ocsar" married Estaline Young and is listed as being a widower.  I cannot find a death record on her, however my great aunt told me this past weekend that she has been to Belle's grave in St. Albans, WV.  But she knew that it was not Cunningham Memorial Park.    Belle is last listed on the census in 1900. But she had another child between 1912-1913. 

Any help would be most appreciated. 

Thanks!
