Robin, Luck was with us this morning. I have that book and looked in the index for you but Noah and Lucinda are not listed. As I turned pages to check a "possibility", I found them on page 253 in the CEDARDALE Cemetery:
Lucinda Jenerette COOPER, Dec. 22, 1843 - June 24 1926, w of Noah B. Cooper
N. B. COOPER, March 4, 1835 - Aug. 5, 1897, b Cool Springs, Horry Co, SC; d Mullins, Marion Co, SC (Confederate Veteran)
Frances Elizabeth COOPER, Dec. 9, 1879 - April 1991, da of LJ & NB Cooper (This stone marks resting place of the first person buried in this cemetery. Beside her lie her mother and father)
Also listed with them are two children but I could not find PS & Leila:
Preston S. Cooper, Oct. 8, 1899 - Jan. 5, 1900, s of PS & Leila M. Cooper
Catherine COOPER, Feb. 14, 1898 - May 28, 1899, da of PS & Leila M. Cooper
When I purchased my book many years ago, the Historical Society included a listing of the Coleman family which the publisher had, for some reason, omitted from the printed index. Now I know there are other omissions.
