Hi Cathy, I have some information on the family you're researching. My late husband's line comes down from Isaac's son Alfred Holland Green (by second wife, Sarah Elizabeth Potts). There are a lot of us researching this family and todate, none of us have been able to prove who Isaac's father was. Your Jacob was married Sarah Cowfer Noss, whom I believe was the sister to Alfred's wife, Mary Cowfer. Jacob's mother was Nancy Goddard (Isaac's first wife). I'll check my records and see what additional information I can provide. Modena Williams.
