Hi Dotty, I was fortunate enough to find a copy of Descendants of Philemon Dickerson by Wesley Baker on Amazon a few months back, so I just looked up some of the info you're seeking and found: John J Dickerson, born in Mendham NJ 3/2/1827, died 4/19/1910 age 84 in Covert, NY; married Elizabeth Brinkerhoff 6/11/1862; their children were 1)Anna 1863-1898 who married Charles Heasley and had 2 children, 2)Benjamin 1865-1900, 3)Joseph G born 1866 and 11/27/1895 married Estelle Palmer born 1876, no children and they lived in Trumansburg (near Ithaca), 4)Lucius born 1870, 5)Adella born 1872and 9/21/1892 married George Palmer who was born 1870, they had 12 children, 6)Lura L born 1875 and 6/11/1896 married Mott Mildrine and had 6 children. John J's parents were Garret and Anna Banker DeGroot Dickerson and he was one of 10 children. Garret's parents were John Dickerson of Mendham NJ and Hannah Bray. This John's parents were Thomas and Sarah Wager Dickerson (Thomas 4, Thomas 3, Peter 2, Philemon 1--the settler). I'll keep looking to see if I can find more info about your other questions.
