Cheryl, According to "Oklahoma Cemetery Records in Lincoln County", New Salem Cemetery is located 6 miles west and 1 mile south of Meeker, OK. (NW 1/4 Sec. 28 T12N, R3E).Inscriptions were taken Feb. 12, 1966 by Indian Spring Chapter, DAR.There wasn't a Daniel Collier listed, however there were:
Nova M. Collier June 30, 1895 - July 6, 1909
Collier, Thomas J. Mar. 13, 1910 - May 12, 1910 Children of W.J. & L. T. Collier.
I don't think anyone has brought the inscriptions up-to-date and 1966-2000 is quite a time span.Did your ggrandfather die after 1966? And have you tried the Lincoln County Museum of Pioneer History in Chandler?They might be able to help. M.
