As David/Edward seems to have been sexually dysfunctional and Wallis unable to have children, [various sources] I think the idea of issue was rather irrelevant. However it apparently meant something in the time. I personally do not care much for either of them, but I like Wallis' style and determination. Edward, to me, was just a whinny, greedy wimpy, always feeling persecuted. one of those people who blame all their problems on everyone but themselves. Wallis got what she wanted- a glamorous life, if not very productive. Beautiful homes, and first class travel. BTW, she refused to fly, so was really a "jet-setter" But preferred the liners. That I can understand, I hate to fly as well, it is such a chore. I think she would be horrified of the likes of Easyjet if she were still alive. I know she flew back to England for David's funeral, but it was like pulling teeth to get on the plane! But, by then, she was a broken old woman. She had quite a colourfull life, to say the least. She made David shine, even if he was an imbecile.
