Hi Kate, your info on Nathaniel appears to be incorrect. The Nathaniel Parmelee that married Althea Whitmore in Newtown, Fairfield, CT. was born 2 May 1694 In Guilford, New Haven, CT., son of Stephen Parmelee & Elizibeth Baldwin.
See Parmelee Family in Families of Early Guilford, Connecticut, Vol. II http://search.ancestry.com/Browse/BookView.aspx?dbid=48019&a...
Attached is page from the book " Newtown's history and historian, Ezra Levan Johnson"
you read it online or download from:http://archive.org/details/newtownshistoryh00johns
I will look at FHL film of Newtown church records tomorow, will let you know if i find anything on Whitmore.
