Looking for a Smith family relative

I am looking for my real dad.
His name is Marion Earl Smith Jr
He was born in South Carolina around 1951
He has 2 sisters. Ruby and Glenda.
His dads name is Marion Smith and
his moms name is Nicole.
My mom's name is Christine Sue Jasman but,
now she is married. Her last name is different.
I would love it if anyone has any info on my real dad.
I have been searching since I was 19.
I think I found him but, I'm not 100% sure. I sent
my mom a picture I found when I was doing a search.
I hope she can verify if it is him or not.
Any info would greatly be appreciated.
Thanks and have a great day.
