Just received a nice note from a cousin, Leon, who connects with me on the King line. His ancestor was Thomas King (1817-1864) and his second wife, Martha E. (Haggerty) King (1830-1912) through their daughter Elizabeth. His Thomas was the brother of my maternal 3rd-great grandfather, Daniel King (1820-1876). The family lived in Madison County, Indiana.
Elizabeth was married to James Franklin Fink. Hopefully, he can share some more detail on his line and I can add more cousins to my database. Prior to his email, I only had Elizabeth's date of birth and no information on a marriage.
It appears that neither of us have discovered the origins in North Carolina of Thomas and Daniel's father, William King (c1790-1869).
