I am trying to locate a Markham Cemetery, also referred to as the German Lutheran Cemetery. I am looking for a Charles Keppel, his wife Ricka Keppel, they died in 1902 and1911, they are supposed to be buried here. Their son, Ernst/Anson Keppel was married to Margaret Schneider, her parents, John and Mary, are supposed to be buried here as well.
I welcome any help or guidance,

Thank You,
