Dickinson/Dickerson Family of Long Island and Saratoga County

I am researching our Dickinson family history. I have uncovered records tracing the family to James Hart Dickerson and Priscilla Rogers. James is likely the son of James Dickinson (b abt 1707 North Castle) and Mary Smith Hart. Uncertain whether James is the son of Joseph Dickinson and Hannah Carpenter (Coles).
I am looking for additional records confirming the family relationship ... and possible connection of James Hart Dickerson as a descendant of Capt. John Dickinson married to Rose Townsend.
Thank you in advance.
