Thanks for the links to the blog posts. I agree with Amy's conclusion that we should use the terms used at the time, just like we use the place names that people used at the time. Putting the words in historical context, as she did with the census instructions about how the forms should be filled out, is helpful and important to do, too, so we can tell what they meant about our ancestors. It can be discussed in the bio or research notes.
I wasn't sure what the community standard was, which is why I asked. I think it might be a good idea to offer some community guidelines about this topic in case people have these sorts of questions in the future.
Thanks again.
