Michael,
Cap'n Milliken is indeed father of Dr. Samuel E. Milliken, a most distinguished surgeon in the Dallas area. Dr. S.E. Milliken also had a cousin who practiced medicine his name was Dr. Samuel Ramsey Milliken; son of William Dickerson Milliken, Sr. of Lewisville, TX.
Contact me directly as we're also cousins (though a bit more remotely).
