Elizabeth GRISWOLD d. 1691

I am trying to determine which of the GRISWOLD sisters was actually m. to Matthew BECKWITH.Some researchers state it was Elizabeth GRISWOLD d/o Matthew GRISWOLD and Anna WOLCOTT.She apparently was m 1) John ROGERS who she divorced;m 2) Peter PRATT and m 3) Matthew BECKWITH in 1690 with whom she had a daughter, Griswold BECKWITH.However, I found a marriage record from CT Records that states it was Sarah GRISWOLD d/o Matthew GRISWOLD and Anna WOLCOTT.Sarah was b. 1647 New London, m. 1666 to Matthew BECKWITH and she d. 1691 Lyme, CT.I actually descend from Edward, the brother of Matthew GRISWOLD but just trying to get my data correct.Thanks for any help.
