I found a marriage license for Howard Smith, age 21, Raleigh, Wake, North Carolina, and Ana Mae Fields, age 12, same place, on Ancestry. Looking at the actual image it has "License not returned" which could mean the marriage probably did not occur.

Other than that, I can't find any other information that would positively identify your Howard Smith. Unfortunately, without a middle initial or name, it's going to be almost impossible to find him as his name is so common.
I'm sorry I couldn't be of more help.
