I think you are right, Anne. I’ve now got two secondary sources that agree on her identity but disagree on her name: The History of the Holt Family (Durie) calls her “Roxilena,” but the Genealogy of the Hitchcock Family (Marsh) calls her “Roxerene.” And the records on FamilySearch are all over the lot:
“Roixanna” (Connecticut Births and Christenings 1649-1906),
“Rorserene” (Massachusetts Marriages 1695-1910)
“Rosserem” (Massachusetts Births and Christenings, 1639-1915)
To make matters even more confusing it appears there was also a “Roxalana” of about the same age who was married to Ebenezer Sumner and living in Ashford, CT at the same time as ”Roxilena/Roxerene” was married to Ebenezer Hitchcock and living first in Hampden County, MA and later in Addison County, VT. There appears to be a record of a daughter, Almira or Myra being born to “Roxalana” and Ebenezer Sumner, but “Roxalana” appears to have died prior to 1789, when Ebenezer Sumner of Ashford married a 2d wife by whom he had a whole passle of children (lots of supporting records for the 2d family). Meanwhile “Roxilena/Roxerene” was still alive and kicking in Vermont up until the 1820s.
There is no way that HOLT-4702 can be both Mrs. Hitchcock and Mrs. Sumner, but since Ashford is just a few miles down the road from Hampton, where HOLT-4702 was born, the Summers contingent appear to be laying claim to her as well as the Hitchcocks (wothout citing any evidence, of course). None of them has cited a marriage record, so that looks like the next sthing to start looking for. No wonder this profile was abandoned!
