My gr,gr grandfather was John Rickert who married Margaretha ??, John was born in 1834 in Wurtenberg, Germany and was a coalminer in St. Clair County Margaretha was born in 1843 in Baden, Germany. I am looking for her maiden name and marriage date which was possibly 1859 or 1860 and also when they may have immigrated over. Any help is appreciated. Thanks. Patti
