I am helping two cousin search for their Native American Park Family. Recent DNA test was completed showed that they are not Scots-Irish but rather Native American. We think the ancestor was adopted in the 1770's by a Park family in PA. and he took the Park name. We would appreciate any help on how to research. Andrew Park and Samuel West Park are two known ancestors. My cousins and I are related on McClain side of the family who intermarried with the Park family
