''Born to'' and ''In to''
''She is the first Puritan figure in American Literature and notable for her large corpus of poetry, as well as personal writings published posthumously. Born to a wealthy Puritan family in Northampton, England, Bradstreet was a well-read scholar especially affected by the works of Du Bartas.''
1) The paragraph above holds information on the little known yet notable poet Anne Bradstreet. What does ''born to'' mean in the context concerned? Would it be the same if I replaced such expression by ''She was born in a wealthy...''?
2) In regard to the verse below, which is the sole authorship of William Shakespeare, what does ''in to'' mean in the phrase ''I was in to despair''?
''Beshrew thee, cousin, which didst lead me forth / Of that sweet way I was in to despair!''
Thank you very much.
