Auguste identified this man as "Pastor" Martens, but I wonder if he isn't "Preacher Martens" who I've heard about from the old timers and have run into his name in various newspaper articles.
The 1981 Manning Centennial article below mentions he married an Ewoldt, a last name connected to this family album.
Pastor Martens - Lyden Studio PREACHER MARTENS
Wilhelm Martens, best known to all in the surrounding area as "Preacher Martens," was born in Schleswig-Holstein, Germany. He was educated in his homeland; and after graduation from the regular prescribed course of studies, he went on to take further studies in religion. He also taught school and was called upon to do some preaching too.
He came to the United States and settled in Crawford County. He farmed and also presided at church services in Aspinwall.
His wife, the former Margaretha Ewoldt, joined him several years later and the couple became the parents of eight children.
In the early days, before the organization of any religious denominations here, the settlers were in need of someone to whom they could turn for spiritual help and since Preacher Martens was also a Justice of the Peace, he married many, many couples and also baptized innumerable children. He traveled by horse and buggy in all kinds of weather to respond to all who called.
He died in 1904.
