I have a John Milton Kellett born 1853, son of Benjamin Franklin Perry Kellett (born 1833) and Nancy Martha Meeks (born 1829.)Benjamin was the son of Young Perry Kellett, born 1796, and Mary, born abt 1807.Young was the son of Martin Kellett,Sr (1776-1800) and Jane Perry.
Benjamin Kellett's third wife, Sarah Dagnall, had a child named Emma Carolina Kellett. The birth year I have is 1877 with the Emma on the 1880 census who is listed as 6.
Could John have been caring for some of his much younger siblings?
