We can only 'assume' you are referring to Delilah Amelia McNair but you 'omit' any help here by excluding the Profiles.
According to Geni, Delilah Amelia McNair (Vann) is my 17th cousin five times removed.
There is a William 'Trapper' Terry, II listed, who Geni recognizes as my 10th great aunt's niece's husband, though 'no blood relationship.'
It helps the Discussion if you include some identification as to who the subjects are you speak of.
Just for the record, Joseph Putnam is my 7th cousin, again, as per Geni; but, you've got all your connections 'Privated-out' so I can't see anything further.
Joseph Putnam is your 7th cousin.
