You might try adding the birth dates for Armand Tschopp and his wife, Clara Erhart. Maybe someone else could add some info.For our line, the Johannes Tschopp family, they immigrated in 1767, but maybe Johanneshad a brother who came or his brother's children. I only think he had a sister Christina Tschopp born ca. 1746 in Ziefen, Basel, Switzerland. Since this family came from Switzerland, maybe Armand did as well.Love to make the connection.
