A cousin of my husband whose family has lived in Sweden for several generations spotted Johanne Sophia Düsing in his tree on ancestry. They are sharing 3x great grandparents Johann Adolf Düsing and Regina Germer who lived at Staven at the time of the birth of most of their children with Johanna thought to be the eldest by the researcher who helped Edward with these records but she was actually the second daughter. She descends from Johanna's only brother Heinrich Friedrich Ludwig Düsing who was six years younger. Heinrich went to Sweden with his wife and two young children.
Genealogy does show how small the world really is. Edward's great grandparents came from Mecklenburg-Strelitz, his great grandmother in 1849 with her mother and sister to join her brothers in the Niagara area (Canadian side of border) and his great grandfather arrived in 1866 in Brant County. I will let Edward's Schultz cousins know as several of them are interested in their family roots in Mecklenburg-Strelitz.
