First of all, surely you realize that it is the burden of the people making he claim that Darwin recanted to prove it, not our burden to disprove it?
Nobody has put forward any evidence that this actually happened - to the contrary, most posters can't back it up with anything more than "I read it somewhere."
Regardless, I am happy to give you another source. Surely you believe Answers in Genesis? No friend of evolution, the site is actually honest enough to admit that this was a fraud.

"(I)t is a pity that to this day the Lady Hope story occasionally appears in tracts published and given out by well-meaning people."
Answers in Genesis has never been considered a dependable source by evolutionists I've spoken with I wouldn't go there either, I'd want an unbiased source.
Also I don't doubt that on one's deathbed they may be quite prone to make a last confession just in case.
