I have records of a David Geer, b. 1755 d.1821 and Susannah Mattison married in Granville Co., N.C. in 1770. The dates aren't the same as yours, but the offspring names are similar: Frederick, John, Willis, Solomon, Lucy, Sally, Susanna, Nancy, Rachel, Karen, Patsey, Gilly. This comes from research done by G.C. Robinson back in 1993. These were found in LDS and other records from Rutherford co., N.C. My known ancestors start with Ransom Geer b. 1802 (possibly in Rutherford co. N.C.) d. 1885 in White co., Tn. There are several references in my collection of papers about a will filed in White co. Tn. for David Geer.
