Kenny says "the genealogy of t he Ogden family revealed that a James Ralph had married Rebekah Ogden, who was born somewhere bet ween 1690-96" (with a footnote to William Ogden Wheeler, ''The Ogden Family in America.'' Ogden states without elaboratiion, "His wife's first name was Rebekah.")
But the Wikipedia entry on James Ralph states (or stated, anyway, on May 29, 2011, at 3:56 p.m. PDT) "the first solid fact about Ralph is his marriage to Mary Ogden in 1724 in Elizabethtown and the birth of the couple's daughter that year in Elizabethtown."
The Edmund Garrigues genealogy states that Mary Garrigues's mother was named Hannah Ogden.
I would tend to favor the Kenny source (I have a copy of his dissertation).
