Should people who make mistakes on counties be put in jail, or just fined? Since family historians range from beginning amateurs to professional, certified researchers, it's more a question of "what is going to help the person with whom you share the information." Someone may know a lot about the location and eventual disappearance of "old" Rappahannock County, but just be starting research on an ancestor from Orange County -- which once included Augusta County -- which once included much of present-day Illinois. So my answer is, the more information the better. If you know that the county changed while the location stayed the same, include it in your records. If the history is not new to the next person who reads it (or the person 50 years from now who reads it), it will be a good reminder. We all need to be reminded of things, occasionally. There was a 9th Circuit Court of Appeals opinion published in April concerning which of two liens on Indian trust land had priority. The question asked here reminded me of the story it tells: >>Peskind’s law holds: When there is uncertainty about where to file a security interest in order to perfect it, file everywhere. Peskind’s law is named after E.J. Peskind, a longstanding member of the Arizona Bar. Peskind was a student of Professor James J. White at the University of Michigan Law School in the 1960’s. When Professor White called on Peskind and asked him what steps a party should take to perfect its security interest when there is uncertainty about where to file, Peskind responded, “File everywhere.” Apparently moved by the wisdom of that answer, Professor White declared to the class that it would be forever known as “Peskind’s law.” The White & Summers hornbook defines Peskind’s law as follows: “When in doubt about your perfection take all possible steps (including . . . multiple filing) that could help.”<<
