Dear Virginia: According to our collective database, there was an Ephraim Whitney, Jr., born 7 Sep 1807, in Newburg, ME. Interestingly, he is the son of an Ephraim Whitney, b. ca 1780, who is shown as having died after 1850 in Tuscawarus Co., OH (unless whoever submitted that got him mixed up with his son that you found in the 1850 census) There is no marriage for Junior in the db, and the info was skimpy to say the least. You might, however, have some luck if you focus your looking toward Newburg, ME. Sincerely, Allan E. Green
