Addie Lou Duggins does not appear on my family tree but may distantly related and I've just not made the connection yet. All I could find on Addie King was that she was born 8 Apr 1907 and died Mar 1974 in Elon College, Alamance Co., NC. Her husband William Monroe King was born 20 Jun 1905 Rockingham County, NC died 22 Oct 1974 Elon College, Alamance Co., NC. I also found one of their children, Irvin Ray King born 29 Aug 1929 Guilford County, NC died 6 Apr 2004 in Lexinton, North Carolina (his obit can be seen on the Courier Tribune obits online). Because Addie and William King both had social security numbers you may be able to get their parents names from those. This info can be found on the SSDI (social security death index) that is online - can be found on ancestry.com and it offers an order form. Sorry I didn't have more information for you. I looked at 1910 - 1930 census records but haven't been able to find them yet.
