Trying to find Birth Father

Hello,
I am trying to find my birth father. I have his name and year of birth. I am finding two possible matches based off of the year of birth. With these two matches, I found 2 marriages (one was to my birth mother) with different last name spelling.
However, I have now hit a brick wall. I am not able to find any other information on him after a match from 1970.
Any suggestions on how to proceed are appreciated.

Searching for the living - or possibly living - can be difficult because records are often closed to protect their privacy.
It would be difficult to make suggestions without knowing details, and we shouldn't ask for those details. This Community is called "FamilySearch" but that doesn't mean we look for living family. There are groups that specialize in searching for birth family - for adoptees or others who do not have a relationship with birth parents. The work done by those "Search Angels" is conducted in private.
