Much of this info was verified in the publication "Howe
Genealogy" by Rev Daniel Wait Howe available on microfilm

Elizabeth Jackson came to America as a 14 year-old servant
in the household of Mr. Ezekiel Rogers to establish the
Rogers Plantation ifn Rowley, MASS. She apparently was
not an indentured servant. This was apparently 1639.
