If you make a copy from a published history or any reference, do you also copy enough of the material so that the item is in context?
A relative copied one page from a county history that is only a list of names. No idea why the list was created, what year it was created, or any other detail as to how the people's names got on the list. Without any idea at all, the list is merely a list of names. They could have been gathered arbitrarily for all I know.
Always include a complete citation and enough information from the original so that you know what you really copied.
A name by any other name is just a name.
