I am researching (along with Rick Roth)the Theodore Merkle family. According to Germans to America, Herr Merkle arrived on the SS. Redwood in NY from Le Havre on May 17, 1854. I believe he eventually made it to Reading, Sycamore Township, OH (outside of Cincinnati) and had a very large family.
His descendants are: Mary, b. 1864 Peter, b. 1861 Rose, b. 1868 Theodore, b. 1870 Joseph, b. 1877 Theresa, b. 1878 Anna, b. 1882 Charles, b. 1887
These may or not be all of his descendants. This information does have sources, and I will be glad to supply them for serious inquiries. Any information would be helpful. I am additionally looking into his daughter, Theresa's family. She married John Schmid and moved to Richmond, IN before 1910.
