I am also descended from Emily Hardman Ingram Argabrite, daughter of Sira Leah Cunningham and Benjamin G. Hardman. Although some records indicate that Sira Leah Hardman was buried with her husband, she is actually buried in the H.C. McWhorter plot in Spring Hill Cemetery, Charleston, Kanawha Co., WV. Her daughter, Mary Leah, was married to Henry Clay McWhorter. I assume that as a widow of 9 years Sira was living with her daughter and son-in-law at the time of her death on 15 July 1874. I have not visited the cemetery myself but have a photo of the headstone in that cemetery that I would be willing to share.
