I just found a home made publication at my father's home entitled three centuries of Derrings. It was sent to my father from the address listed in this thread. It is a legitimate document that compiles many records of our family name from census records, military records, birth and marriage records and more. I just wanted to put this out there as at least at some point in time (I have no idea when my father ordered this) this seems to have been a legitimate organization or person. FYI they also list other names similar to ours, suspecting that there may be a connection (I say that as a former poster stated that his family name was misspelled).
