Grandmother and other relatives always said a certain person was my dad, My mother denied this. This person had kids with someone else. All parents deceased.
Can DNA determine if this man's other children and I are related. Which would mean he's my dad.

In a word - yes. Of course, they'd have to consent.

Thank you for the response. I asked this question because, I checked the DNA testing sites and each one seemed to indicate that the potential half siblings could only determine if they had the mother through the DNA testing if no parent DNA was available

As I recall - and you could call a testing lab to ask - you can also determine paternity.

There's an old thread on this. I wonder if someone can find it. I believe the question was the father. In fact, I'm sure it was and it boiled down to inheriting.
