I found this old post and might have a few informations for you. Taaffe was married for the second time after the death of his first wife to a relative of mine, Victorine Juliane Bøgh (1841-1919). I have some pictures of her, of Taaffe and of his children from his first marriage, surname Schultz. I think I have some letters too from some of these people. I am interested in learning more about Taaffe's origin.
