From page 765 of "The History of the American Negro North Carolina Edition" states that

"Dr. O'Kelly has been married twice. His first marriage was in 1900 to Miss Corrinne L. Gibson, a daughter of John and Annie Gibson. She passed away in 1903. On August 4, 1905, he was married to Miss Cora A. Bass, a daughter of Ransom andCaroline Bass."Page 763 of this same book has a photo of Dr. Cadd Grant O'Kelly!

Thought you would all like to know....I found this online through the Godfrey Library. You can go to Godfrey.org and check out their Godfrey Scholar membership. Through this membership you have online access to many different online databases that you cannot subscribe to as an individual. I am not affiliated with Godfrey Library in any way. I only want to share the best online resource to access info I have found.
