my mother (Lois Murial Lightfoot) was the daughter of Vivian Anna Baumann-Lightfoot & George Robert Lightfoot
Anna Bauman was the daughter of the Iba, I found this written on the back of a photograph of the Iba's have a bunch of them , very old. Also written is Spain and Germain, "Iba family" Mom's grandmother. When I have some time I can PDF file it to you. :-)
Also the Amanu (may have been Amann) Christina Amanu is written as a godparent on a german baptismal certificate for Elisabeth C.Baumann & the name Christina Santina Baumann is the mothers name on it.
How are you related to the Iba family?
Pleasure to meet you, hope we can help each other with research.
