You have his FAG memorial info.
South Carolina started recording births 1913, therefore, there is no point in looking for his birth certificate.
I'd look for John M. Dickson's probate records and hopefully Sam/Samuel will be listed there.
I'd look for Sam and Denisia's marriage record. Both sets of parents might be on it. If not, I'd look for their newspaper marriage announcement.
I didn't find his death certificate online and South Carolina started recording deaths in 1915. Contact the South Carolina Archive, www.archivesindex.sc.gov/guide/CountyRecords/cityguide.htm
and ask them if he had a death certificate or not. If the Informant knew his parents names, they will be on his death certificate. Successful Searching!
