The info I have from the Fisher Genealogy by Philip A. Fisher; Everett, MA; Massachusetts Publishing Company, 1898; pg 305 reads as follows:
David, son of David and Nancy (Chandler) Fisher, was b. at Plantation No. 3, now Charlotte, ME., Dec. 22, 1810; m. at Dedham, MA, Jan 9, 1949, Sarah, daughter of John S. and Ann ( ) Merritt, of North Livermore, ME, who was b. there, Jan. 16, 1821. They res. at Chelmsford, MA (1895.) Their children were:
1. Mercy Jennie P., b. Feb. 3, 1850; m. Henry R. Hodson, Jan. 20, 1868. Res. Chelmsford, MA
2. David M., b. in New Boston, N.H., April 17, 1854; d. Aug. 21, 1855.
3. Oscar C., b. Dec 15, 1859; d. Dec 8. 1860.
4. Flora A., b. April 5, 1862; m. Ernest Nettel, Oct. 1, 1887; two children.
This book takes the Fisher line back to England and 1585.
