In the book, Old Gravesites Revisited, Gaston and Lincoln Counties, edited by Mrs. Paul E. Rhyne, Mrs. John A Grissop, and Mrs. Terry Waldrop, presented by The Historical Society of Lincoln County, June, 1986, there's a Linebarger Cemetery at "From Jct. Hwy 321 & Hwy 279, take Hwy. 279 West abt. 1 mile, L on Gaston County Park Rd. 1.3 miles.Below Mrs. Howard Pasour's house, ask her permission..." that has the following: 10-(A) Lineberger, Jonas L., Father Dec. 1, 1820 May 6, 1898 10-(B) Lineberger, Lanie S., Mother Apr. 1, 1829 Sep. 18, 1904. This may or may not be the Jonas Laban Linebarger whom you seek, but it's a lead.If I remember correctly I copied this at the library at Lincolnton, N.C.
