Our records contain a Willis KUYKENDALL (3rd cousin, 3 times removed) that was born abt 1861 in Manchester, Coffee County, Tennessee. He passed away about 1900 and we don't have a site. He married Gabriela Ellen COOPER on Aug 29, 1885. Her info: b. May 12, 1862 in Ponchatoula, Tangipahoa, Louisiana and passed away on Oct 16, 1945 in New Orleans, Orleans Parish, Louisiana.
Willis & Gabriela had 4 children: Beulah Francis KUYKENDALL 1867-1960, Edward Lee KUYKENDALL 1887-1946, Charles Neal KUYKENDALL 1888-1954 and May KUYKENDALL 1895-1963.
It has been a long time since I've done any work on the KUYKENDALL branch of our family tree and I'm sure the sources for this Willis & Gabriela were not added when they and their children were added. Maybe there is something that might at least give you another place to look.
