Hi, Barbara. Even letters that don’t give out exact genealogical data are important if only because they record personal accounts of individuals or even business transactions. Day to day happenings flesh out (so to speak) the lives of senders and recipients as well as others that might be mentioned. In my personal database, I have included letters in the notes sections for the above reasons and, sometimes, for personal reasons if I knew the sender/recipient. Also, I have this penchant for saving anything that remotely is connected to relatives past. So, I’d say, save those letters! You’ve got a treasure.
