It sounds like my Anna Marie Acker (b. Oct.19, 1830)might be the one in your Acker family. She came from Alsace-Lorraine to join her brother, Anton, in Wisconsin, who had come over earlier. She came via Buffalo, NY. In Racine County, WI, she met Theodore Schweitzer and married him in 1854 & they settled on a farm in Oak Creek. Later they moved to St. Martins (Franklin), WI.She died Feb. 24, 1891.
