I am getting no where with my searches so I thought I would check back and see if anyone else had any luck? :-/ I know now that Gertrudes mothers name was something along the lines of herminia / hermina / wilhermina and her fathers name was Carl Lehmann. Her step-father we know to be Adolf Fischer of 81 Wilhelm st, Nowawes Germany (in 1923). She also had an uncle or some relative named Otto H Reinhardt who lived in Central Falls, RI USA.
I am really struggling to find any information on any of these relatives.
