Have you found out anymore about Franklin Henderson b. 1850, d 1877 since you posted this?
I have a mystery ... my ancestor Isabelle Ellen Mccourtney is shown on the 1880 Federal Census as having 2 boys ... Franklin b abt 1875 in MI, and Charles born abt 1877 in MI ... their father listed as being born in PA and Isabelle being born either in MI or IN. (Sources disagree).Problem is Isabelle married Harvey Sanders (Saunders) in Mower County, MN July 30, 1879. Their only child Mary Ellen was my great-grandmother.My grandfather never knew about the two boys.So where did they go?And who was their father?
Can you shed any light on this baffling dead end for me?
