Her name easily could have been Elizabeth as their first daughter was named that. She wrote a will in 1669 in North Petherton that was destroyed in the bombings in World War II that would have proved this one way or the other.
Elizabeth married Marmaduke COATE  [MRIN: 5954], son of William COATE  and Unknown , before 1671. (Marmaduke COATE  was born before 1626 of Somerset, England 2 and died after 1688 of Curry Rivel Parish, Somerset, England.)
