Hi Linda: Checking your posting I see we are interested in same family of your Silas Alexander b 1791 KY. I think he is brother of Samuel who received land from William, and maybe the same William Alexander who in May 1808 received a Warren Co land grant adjoining land with a John Graham, John Looney and John Derryberry all who may be from Silver Creek of Burke Co,/ McDowell Co, NC.
My relative may be the Ester Graham a possible sister of my John Graham b 1792 NC who married 1814 in Cannon Co, TN Lydia Rushing by Rev Randolph Malicah Hollis, and the witnesses given to their Wedding was your Silas Alexander and Ester Graham.John's family & Silas Alexander's migrated to Lawrence County, Alabama about 1816 where my John Graham later conducted legal transactions with Silas's son father in law,Woodson May.
Also you are noting that Silas's daughter Rhonda Dora married James Richardson, and would be interested in knowing if he is related to Sarah Richardson who married Levi Isabell of Lauderdale Co, AL and a Levi Isabell who married (2) a Mary Looney d/o Thomas Looney.
Any information of Ester Graham sibs and parents would be most helpful. Dennis
