I would consider it suggestive, but not definitive at that distance. If your mother and father came from the same geographic area it isn't impossible that they were distant cousins. It could be someone else from his family. Part of the problem with doing DNA is that a lot of the comparisons / hints requires both parties to have accurate trees (Thrulines uses family trees, which may be incomplete or incorrect) and for people to have tested in the first place- no comparison if no DNA.
Start with the matches closest to you and figure out where they fit in- add notes on their match. The more people you figure out, the more information you have when you look at Shared Matches and see notes for the same branch or two. The part that says "Parent 1" and "Parent 2" can be allocated to "mother" and "father" once you figure out who is who.
As a clarification to Peter's post, living people's details cannot be shared publicly on this site for privacy reasons, so if your mother and (suspected) father are or may be still alive, such details cannot be shared here. That makes it a bit difficult for us to help with DNA matching, since you are essentially trying to connect with current living people. We can help look for people further back though.
