Well, I was amazed myself when your reply popped up in my inbox today. It has been nearly five years since I posted that on Genforum.
No, I had never heard of any of that. Whatever we were told about the Nazi period was sanitised considering the times we were living in, I suppose. I was shown the Altenstadt coat-of-arms, of course, and the Oettingen arms are famous. I was not shown them combined, and certainly not with Hohenlohe and Rechberg. And I never heard of the names Hohenlohe or Rechberg being combined with either Oettingen or Altenstadt. In fact, it was made quite clear to me that Oettingen and Altenstadt could not be combined.
Whenever it was discussed within the family, it was clear that we could only claim the coat-of-arms of von Altenstadt and, at most, the title of "Baron". The princely status of the Oettingens was something to which we had no pretensions. Little wonder that, having reached so high but then fallen so low, this was not mentioned.
But the coat-of-arms you describe and the pamphlet eerily sent chills down my spine as I read it. I cannot be certain at this remove, but I seemed to recall once finding a box in the attic when I was very young, oh six or seven or so, and seeing a long thin flat booklet like the pamphlet you describe with a lady's picture (I did not think of my grandmother) and an elaborate coat-of-arms on the right hand page facing it, with several helmets resting on the shield, which was an elaborate quartered shield, I think with a centre-shield quite possibly of Altenstadt, which I had seen. In fact, that may have one of my earliest memories of my interest in heraldry awakening. I was possibly too young to read much English at that age but I do have the impression that the books in that box were printed in German. In fact, several of them I am certain were in the older typeface.
I may have seen that box only a few times between that first exploration and leaving for college as a young man, but I do not think that I ever looked through it again. I do not know what became of it.
I would love to see a copy of the pamphlet if you have it. Please email me directly email@example.com so we can talk further about this.
