Thank you for your efforts. To keep the public record straight, the Lehms I'm searching for came through New Orleans also in 1852, as father Chr. and sons Chr. and Fr. which are also on Ancestry immigration records. A search will also produce the Chr. and Fr. you show, but arriving in Texas. The family I'm searching also has people in the Des Moines area.
But I'm still looking for someone who can explain what happened to Friedrich's grandson Louie Anton's apparent first wife Carrie Madison, m'd 1919, and at least one possible child.
