Daniel Harris - yDNA discrepancy

Note: Harris Y-DNA is fine the discrepancy is the Tyner but is verified Harris lineage coming in from maternal Harris.

Would say, Daniel Harris was Adopted - probably a sister had a baby with a Tyner, and the Harris family raised this child.

Who was his birth mother and father?

It definitely wasn't Daniel C. Harris - although perhaps one of his sister's child?

Definately not Elizabeth Starnes Harris.
