None of the given names you mention ring a bell.
What I have determined since originally posting this message a number of years ago is that Ezra Cole (my third great grandfather) had the following sisters: Anna married Isaac Cornwell Jr.; Mary (Polly) married Nathan Cole; Olive married Barnabus Eaton; Philenda married Luther Stevens; Sarah (Sally) married Henry Govin. The oldest sister, Lucy, is unaccounted for and we must presume she died young.
