Some family trees on Ancestry.com show her date of death as 19 Oct 1852 in Scott Co, Viriginia, but they show the same date and place of death for her daughter Rebecca, so almost certainly one of those is an error. (I am not even totally convinced that the attribution of Silas Easterling’s wife Rebecca as William Elam’s daughter is correct. Not that I have any specific reason to doubt it, just that it is unsourced.)
