That sounds really interesting. I have original copies of letters sent to Hobart's father in response to his inquiries about his son's death. There are at least two letters, possibly three. I can check tonight when I am home and let you know.
These are very old documents (1865). I am hesitant to scan them as I am not sure if that can damage them. I can try and take photos of them if that might help your research. I could try and transcribe them but they are hard to read. If the information can be of assistance I would be happy to help out anyway I can.
