This is where I also rely on Sureties.  We have all of the tools to manage our data in the way that best suits our individual "wiring".  So indebted to Bob and the crew that developed this software. JoAnn This sounds reasonable to me. Especially if your sources only date from the 1950s. I have a few of those kind of Sources and while most have been found to be 100% accurate, I have only included then to remind me where I got the information (and wasn't something I made up). Other than that, I also have an added Source that simply says this data currently has no solid contemporary evidence supporting it -- so beware. Once I do find contemporary (or solid secondary) evidence, I cite that and delete the earlier two Source (especially the warning citation).
