Strickland Family - William in Opp Alabama

Looking for information on my mothers side of the family.  My great grandfather name was William Issiah who married Claudia Estelle Morris(spelling?)  They were married in Opp Alabama (Covington County) around 1910-11 and family information says they are both buried in Leaksville, MS.  William's father was John Strickland and his wife was Nancy Sanders.  Any help is appreciated.  Thanks
