Hello, Reiner! Small world!!!
Heinrich Bartold von Thaden was my great grand uncle (married to Adline Tribbe) ...he was sister to my great grandmother Katharina von Thaden Reppenhagen. Their daughters, Elsie and Irene, were my first cousins twice removed... I suspect, therefore, Elsie and Irene were your cousins as well.
Give me a few days and I can send you pix!!!
Please send me your email address... mine is firstname.lastname@example.org
