One thing, despite the what we have in the drop down menu, the Massachusetts Bay Colony was replaced by the Province of Massachusetts October 7, 1691. Either "Massachusetts" or Province of Massachusetts Bay is probably acceptable, but Massachusetts Bay Colony is actually wrong.
The States Historic Place Names tab of the Data Doctor Spreadsheet has the 'place names' for all of the US States, with the dates when it was used.
Hopefully, this will give you the information that you are looking for.
