Changing the course of history would have been hard for one woman, especially given all the issues involved. But I do think that if Ella had married the Kaiser, they would have made a very interesting couple, to say the least. They were both interesting, dynamic people, and they might be remebered fondly as one of the great royal couples had they surmpunted their individual differences and been united. It woudl have been hard to be united if their son or sons proved to have hemophilia. I myself don't think Ella was a carrier, but we will never know. I don't think the Kaiser would have much liked hemophiliac sons, of cpurse, and this might have created issues. Ella would never have married him, though, as all powers were against it, ( thus, no pressure), and she never cared for him personally at all, in fact disliked him.
