I am guessing that you have the following record also:
Holt, Harold S. 64703720 b. unknown d. Oct., 1967 Southern Memorial Park Biloxi Harrison County Mississippi, USA
Interesting there was a Lillian Holt at the same cemetery who also died in Oct. 1967.
I saw that Daniel B. Holt was cremated; wonder if his ashes are in an urn or if they were given to a family member?The Silverbrook Crematorium & Cemetery might be able to give that info if you haven't contacted them yet. I was able to find out this information concerning my great-grandparents who died in the mid-1940's whose ashes were given to my grandmother.
