Hi Kay and others, No, I do not have any information on where William BLACKBURN and Sabra GIBSON are buried but a good possibility is Washington Co, AR. Sabra was born in 1829 in VA but her parents are listed in the 1840 and 1850 censuses of Washington Co, AR. My wife is a descendant of both the BLACKBURNs and GIBSONs so we would like to develop more information on the lines but we have two of those brick walls. Wish we could help. Joe Carroll
