Am looking to find this info on Nelson Knapp - birth/death dates, where he was born, parents name, etc. He married Martha Edmunds (B: 1816 D: 1874), don't know the year they were married. They had several children - Ruth (B: 1840 D: ?), Abigail (B: 1841 D: 1886), Charlotta Anna (B: 1846 D: 1894), Susan Almira (B: 1849 D: 1873), Augustus Edmund (B: 1851 D: 1898), William (B: 1856 D: 1877), and Charles Franklin (B: 1859 D: 1903).
