I am writing a study of the relationship between Susannah Martin and the 1875 poem "The Witch's Daughter" by John Greenleaf Whittier. As you probably know, the description in the poem of Susannah's arrest, trial and execution is quite accurate; but the "daughter" of the title, "Mabel" Martin, is a heavily fictionalized lass who does not bear much resemblance either to any of Susannah's three real daughters or to her one stepdaughter. Whittier had an expert's knowledge of the 17th-century Puritan culture; but it's clear that in this poem he was writing a romance, not a history lesson. I have read in several places that Susannah was related to Whittier. I am trying to pin down the specific relationship, but have had no luck so far. I am related to both of them -- she's my 9th great grandmother and he's my 4th cousin 6 times removed -- but I can't link the two of them up to each other. I'd be grateful to anyone who can point me in a productive direction. Richard
