James Browne (1604-1676) was twice married. His second wife was Sarah Cutting (Cutting-51) whose identity is reasonably established on WikiTree. It is the identity of his first wife that is in question--specifically, was she the sister of his second wife?
As far as I have been able to learn, this is not a case where Capt. John Cutting, Sarah's father, had an unaccounted for daughter, "Judith" who might have married James Brown(e), but the reverse. In other words, the identity of James Browne's second wife is known, from which springs a notion that she was somehow related to the first wife.
James Browne's first wife appears in the records with the given name "Judith" or "Elizabeth" and was the mother of several children. The claim of a sibling relationship between the two wives was advanced/published by Thomas Bellows Wyman in _The Genealogies and Estates of Charlestown_ 1:271 (1879). Wyman listed two children, Judith and Sarah, saying, "Daus. Of John [Cutting] of Newbury; m. successively, James Brown."

(1) In his treatment of the Cutting family, Walter Goodwin Davis challenged Wyman's finding. Davis expressed doubt that "any seventeenth century magistrate would have married a man to his deceased wife's sister," mentioning the 1720s case involving Thomas Harris and Sarah Duley.
As well, Davis points to the will of the father, Capt. John Cutting (1659). The will mentions John's daughters "Mary the wife of Nicholas Noyes," and "Sara Browne of Charlestown, the wife of James Browne." There is no mention of any other daughter, deceased daughter, nor children that would be attributed to such a daughter. As Davis expresses, the void is pronounced in terms of Cutting's final disposition clause. Should his granddaughter, Mary (Cutting) Moody, die without heirs, Cutting wished her legacy, "be divided between his daughters Mary Noyes and Sarah Browne and their issue ..." As I read Davis' point, Cutting would have effectively "cut off" [Davis' term] the children of any such daughter Judith (but not those half-siblings born to the purported sister, Sarah).

(2) As part of the Great Migration study project, Robert Charles Anderson's profiling of the husband, James Brown, also did not find the first wife to have been Judith Cutting. [_Great Migration Begins …_, 1:252] Anderson calls the first wife "Judith/Elizabeth ____." Citing "EPR 3:110," Anderson describes an entry in the inventory of James Browne for funds held and "due for legacies for four children which Mr. John Cutting gave to his grandchildren & was James Browne's." As Anderson has reconciled the births of Browne's children, none of the "four children" recognized as grandchildren/heirs of John Cutting could have been born to Browne's first wife.

Note: I'm not wondering how to handle this in a personal file, this inquiry has to do with how WikiTree-ers would like to see it handled. Thank you in advance.
