Cheska Wheatley was also researching this family MILLS. See her research posted on Internet, I did not keep ref web site, as it did not take me anywhere with my NJ MILLS. Her postings were back 1998/2000. She had James MILLS as William's father. Also some refs about James MILLS Sr & Jr but could not find documents to prove its link. There is a book about early plantations in Virginia I browsed through in the Culver City, CA public library, in history department about 1989 or so. Has maps etc re locations of MILLS plantation. pat cw
