I am in agreement with a category for people who lived in a territory before it became a State. The category should include all people who lived in that territory before it became a state, including the children of families that moved as a unit. Being a child on the frontier was just as tough a life as it was for the adults. Children born after the territory becomes a State are no different from people moving into the the State after it becomes a State.
When a territory becomes a State, then the conditions for commerce, public schools, social organizations, justice, and law enforcement have been formalized, and the character of life changes dramatically and rapidly from that time and into the future.
A case could be made for an Early Citizens category, to tag those people who helped develop the new State into its present form, and which would apply to outstanding people who moved into, or were born into, a State during the first fifty years of its development. Early Citizens played a unique and meaningful role in the development of a community, whether it be a State, County, or City.
Having clearly delineated categories for Pioneers and another for Early Citizens, will be helpful for future students of history to more clearly understand the dynamics of humanity's social developments.
