I was trying to locate Sina Elizabeth Cooper Pettus on the SSDI using every conceivable combination of names, without success. I then took a look at the Family Search pilot site and found her on the Alabama Death notices for 04 Aug 1967 in Talladega. Her spouse is listed as Elbert Wilson Pettus, with kids, Doster, Austin, and Clarence. I assume this is the same person?
I was following the Cooper line when I stumbled on this Pettus connection. Sorry I can't help you with your Phillips question. Good Luck
