It's worth a look-see. It's possible he may be one and the same. The John I'm looking for had only one daughter (to my knowledge) and her son or grandson eventually was the governor of LA (John Milliken Parker).
What info I have is at home, but I'm looking to see if John/Johnny Milliken was a descendant of Charles Millakin. I believe John was originally from KY.
Thanks for your help!
