for Place Names of areas now USA & Canada, see https://www.wikitree.com/wiki/Space:North_American_Place_Names - from https://www.wikitree.com/g2g/613838/north-american-place-names-updated
For Virginia specifically, see also https://www.wikitree.com/wiki/Space:Virginia%20Place%20Names (but the short answer is 1768 would be Colony of Virginia - 4 July 1776 and after would be Virginia, USA)
I just looked at the wikipedia articles on Virginia and New Jersey. I am not aware of any official wikitree list.
