(are you following me here?)

Johan Wilhelm De La Marck and Anna Van Aldekerk (1564-1616) had Herman Op Den Graeff (1585-1642) in a morganatic marriage.  (And this was the break from the royal family). 

After investigating further, I realized that there is some debate as to whether or not Herman Op Den Graeff was really the son of De La Marck – so it will remain a mystery for now whether or not the royal tie-in truly exists.

Herman Op Den Graeff and Greitjen Pletjes (1588-1643) had Isaac Herman Graeff (1616-1679)

Isaac Herman Greaff and Greitjen Pieters (1620-1683) had Herman Isacks Graeff (1642-1708)

Lewis Edward Latshaw and Nettie Frances Hoffman (1893-1980) had Oral Grethel Latshaw (1914-1980)

And Oral Grethel Latshaw was my grandmother!
