My family is distantly related to the Martins of which you speak...I think.
My gr-gr-grandparents were Philip and Maria Schoenhals. Their daughter, Maria, married Philip Martin, son of Peter and Wilhelmine (Fischer) Martin on May 8, 1900. The Schoenhals's oldest daughter, Caroline, married the Reverend Wilhelm Hinnenthal, Pastor of St. Paul's Lutheran Church in Franklin, in June 1877.
Wilhelm is my great-grandfather. His first wife, Minna, died as a result of complications from childbirth; their daughter Wilhemine, was baptized by her father on July 9, 1876. The following baptismal entry in the church books is that of Georg Carl Martin, son of Peter and Mina (geb. Fischer)Martin, on July 12, 1876. Godparents are Martin Martin, Carl Fischer and Frau Weiss. Is this the George Martin to whom you are related?
If you look at the 1880 census for Peter Martin and his family, the Hinnenthal family appears a few lines ahead of them. We have often wondered if Mina Martin nursed her son and my gr-aunt due to the children's closeness in age. My father's middle name is Martin and over the years we have come to the conclusion that it was derived from a closeness between the Hinnenthal and Martin families of Franklin.
In any event, would love to connect, if you are intereted. I am especially interested in tracking any living members of the Philip Martin / Maria Schoenhals marriage, if you are in contact with them.

PS - I believe that St. Paul's does have a cemetery...I remember finding Minna Hinnenthal's grave many years ago. My recollection, however, is that it is not physically "attached" to the church but is a short distance away. If you are interested, I can check with my dad who will probably recall the specifics better than I.
