You will find good stuff in the Mark Twain-Howells correspondence. I don't have the volumes here at the office, and it's been a while, but both men lost daughters of about the same age, as well as losing their wives. I remember one letter from Howells about visiting his daughter Winifred's grave and quoting Emily Dickinson. It seems a little cold-blooded, given the subject, to wish you HAPPY hunting, so I'll just send good wishes for your project. Peg Wherry
