I have been able to trace my Metlin ancestry to a Thomas Metlin who shows up on the 1850 Summit Co., Ohio census as being 42 years old, born in PA.Bucks Co. has come up in my research before.He was married to Eliza Ann, 46 also born in PA.
Their children are listed as:
Margaret Ann, 16, born Ohio James A., 14, bor Ohio Jane, 11, born Ohio Sara E (this is Sara Eliza), 8, born Ohio Thomas W., 5, born Ohio
Do you have any information on this line of Metlins?
Also...a little family anecdote.My father told me there is a story that two Metlin brothers fell in love with the same woman and there were hard feelings over it.One won her hand.The other became angry and changed his last name from Metlin to Maitland.I don't know if this is true or not.
