Help Needed if possible

Hello everyone,

I did an ancestry dna test about a month ago because I wanted to learn more about my lineage and family history since a lot of it was unknown. Along with that I have never met my real father and was curious if I could match with him or any of his family. Fast forward and I matched with a potential 2nd cousin or half great aunt and a lot of 3rd cousins. I’ve been told by my mother who my father is but I have nothing to back it up besides her word. So I was trying to see if anyone would be able to pin point who my father is based off of my dna matches, from the other relatives. I’m not sure if it is possible but I guess I would rather ask and see than not.
