In searching for my own Allens from Corsicana, Navarro, TX I found the website for Oakwood Cemetery in Corsicana on:
William Dixon Allenb. May 14, 1852 and died Nov 25, 1922 if buried with his wife in Oakwood Cemetery, Corsicana, Navarro, TX
Elnora Carroll Allen b. Jan 20,m 1869 and died Nov. 27, 1957 is buried in Oakwood Cemetery, Corsicana, Navarro, TX beside her husband.
Hope this helps.You can find the Sexton of this Cemetery as under the City of Corsicana Parks and Recreation Department.
I believe the current parson is Sharla Allen (kin?) There are 27,000 graves in the cemetery - one of the oldest in the State of TX. 2 Sections are set aside for IOFF home residents.I don't know what that means...except that my Allen obit. referred to IOFF.
