Thanks for the details and the info,my knowledge is not so detailled in that point, I must confess, was too long concerned with other things. But I was concerned with so many incertain cases in history, especially with illegitimate children and so on, that was the reason, I asked. But why did Alfred carry the name Hortenau? Did Julius accept him or let him have his name? Or did the emperor decide it? There are other cases in history, where illeg. children later carry the name of their mothers husband, even when he is not the father. Was it like that? Were there any special reason that Franz Joseph wanted her so marry Hortenau, when she already had the children and lived with Otto?
It´s quite strange that Otto lived together with his mistress...poor Maria Josepha, I guess. I know I asked this question before, but it would have been interesting to know, if there had been a contact between Alfred and the later Karl I, as they were half siblings, but I suppose Karl and Max lived with the mother, and did not know the half siblings well, or was it different?
