Of particular interest was the following in your post: "Leo Edwin Oberwarth, born 1897 in NY, died 1971, in Franklin County, KY, married 1925 to Zanna Faith Porter, born 1902, in Hampton, IA, died 1984"
Unfortunately I do not have information on the Oberwarth family but I do have information on Faith Porter, her grandfather C. Harry Porter and the Porter family.My great grandfather was Orville Porter brother to C. Harry Porter grandfather to Faith Porter. Cora Porter (daughter of C. Harry Porter is buried in Kentucky) and I believe she lived with Faith and Leo later in her life.I am willing to share any information I have with you regarding the Faith Porter's family from Hampton Iowa.FYI. John Ossian Porter was Faith's great grandfather.
If you would like any information on the Porter's please contact me at firstname.lastname@example.org I'm happy to share information that I have.
