While I am absolutely sure that no harm was meant by the person who posted the letter in question, and that it was done in a spirit of helpfulness, I am not sure that it is appropriate for us to post personal letters, regardless of whether the principals are dead or how long ago they may have died. I know that I don't want my own letters posted on the internet after I'm gone, and the only people who can prevent that happening are those into whose hands they may fall. Maybe, in the case of personal letters, it would be better to first post a query, asking whether anyone might know of the addressee or of the author. If there is an interested response, then maybe the communication about such a letter could be more private. On the other hand, posting general queries, items which are of public record, or citing sources where information may be obtained is just fine, in my opinion. Pip
