I've read many of your articles on Morphy, and really enjoy them, batgirl. You are opinionated and identify yourself as a "Morphy Girl".
I used that term not because I have some super-attatchment to Morphy, but because I had written so much about him in the past, particularly because of my Paul Morphy website... people would ask, "Aren't you the Morphy girl?"
Batgirl, what do you make of the contention that Morphy manufactured illnesses and was actually quite ill-mannered towards Anderssen and Staunton. He forced Anderssen to come to Paris to play him, and may actually have been the one to avoid Staunton rather than the other way around?
I was reading some of the letters that you provided by Edge and Fiske, and some of the quotes by Anderssen and Seargant. They paint quite a different picture from the hagiographies on Morphy.
The Germans, particularly Max Lange, were a little unsettled that Anderssen accepted the match without consulting them. Morphy never challenged Anderssen, although he had initially hoped to go to Germany to play him. A situation arose while Morphy was in France (waiting for Staunton to finalize their proposed match). First, he had every intention to be home by Christmas and his family was pressuring him to leave - eventually, they sent his brother-in-law to fetch him. Ever since arriving in France, Morphy suffered from a chronic intestinal illness - part of the reason he refused anything to eat during his 10 hr. blindfold ordeal in La Regence was that he was afraid that if he did he may have to leave the room and didn't want to be suspected of cheating. His illness wasn't faked and had been confined to bed starting several weeks before Anderssen arrived. Anderssen, however, suspected it might have been a ploy... but then again, Anderssen may have wanted a reason to lessen the sting of losing so badly (Anderssen later offered other excuses).
Back to not traveling to Germany: soon after his match with Harrwitz, Morphy realized he couldn't go to Germany and return home by Christmas, so he abandonned any hope of playing Anderssen. His self-appointed traveling manager, Frederick Edge, took it upon himself to secretly engage in a mail campaign to convince Anderssen to come to France. Edge also went behind Morphy's back to get a doctor to write to his family, convincing them he was took sick to travel (which may, of course, have been true). Once the match was a done deal, Edge revealed it to Morphy. Morphy did become excited at the prospect. But Edge's machinations - he had many of them, including writing an unauthorized book about Morphy - resulted in Morphy servering all connections with him right after Anderssen left for home.
There is nothing to indicate Morphy's actions or his dealings with either Anderssen or Staunton were anything less than honorable and gentlemanly. Anderssen, while also praised for his comportment, comes across less benevolent in his correspondence with Lange and v.d. Lasa. There was also a backlash from comments culled by Edge that Anderssen made, somewhat skewing the perception of Anderssen's feeling. Staunton's behavior was very much less than honorable and he was sanctioned, although mildly, by Lord Lyttleton and all but one of the English chess clubs - none of whom/which wanted to get on Staunon's wrong side.
I can't think of a single persom, other than Staunton, who had anything negative to say about Morphy's behavior... and in fact, most people praised him highly in that respect. The Germans weren't so much critical of Morphy (Lange, v.d. Lasa and Falkbeer actually thought very highly of him) as they were dismayed that the Anderssen match took place in a manner they considered situationally in Morphy's favor.
