I don't think our rebecca is the same as person as yours but some how they must be related. My husband's great grandparents were Ira and Rebecca (Sarah) Wiggins Furbush. They lived in Church Hill MD. In fact from what I understand they owned a store there. Rebecca's brother was Albert Wiggins. She was a firey red head from Ireland- quite the tom boy I am told from our Uncle who remembers her. She is buried at the Sudlerville cemetery listed as Sarah R. Furbush,1883-1955.
Their sons were from Newark De, so I can't help but think that this line must some how be related. I have not looked into the Wiggins side of the family yet, still trying to figure out the Furbush line!
