Loren, I find that David Fisher and Elizabeth Wright were married 16 May 1839 in Clinton County. So the Wright children listed in the 1850 census for her and David can't be Elizabeths if they married in 1839. The children have to belong to deceased Ezekial and Orpha. So Elizabeth may have been Ezekial's sister. Or if she was previously married to a Wright, as you suppose, she may have been a Matson. Confusing. However, to add more, David Fisher was previously married 1st to Hannah Clevenger, Adens sister. And she died in the 1830's. So there are probably Fisher children of David and Hannah Clevenger, born Clinton County between 1813 and 1838.
