You contacted Mark over email about a thing he has been in court over and over and years after the court decision you actually think he will reply to a stranger and tell him everything? For real?
Anyhow, since we're at that level of communication and information, why don't you contact Craig Wright also, he claimed he owned that address, and since the first transfer to it was the funding one he was also the hacker, of course then he miraculously lost somehow everything related to that address but I'm pretty sure his lawyers will give you any information you want. 


And from who do you want to claim damages? MtGox? You might be a little late for that!
