Find a Grave, I discovered a reference for this woman, Abigail FISH, daughter of Samuel FISH and Sarah STARKE. She is referenced there as being buried in the BURROWS Burying Ground in Groton, CT but she is not buried there, she is buried in the Old Packer-Burrows Burying Ground. (I am sure there was confusion since both graveyards have Burrows in their name!)
Abigail's gravestone is quite amazing. It lists her parents and both her husbands. Her first husband was Cap't Daniel ELDREDGE who she married 26 June 1711. After he died she married Deacon Daniel DENISON, Sr. as his third wife! His others were Mary STANTON (my ancestor) and Jane COGSWELL.
He is buried alongside Mary STANTON at Elm Grove Cemetery in Mystic. Cap't Daniel ELDREGE lies buried here at the Old Packer Burrows Burying Ground.
