Hello. Could we / I add this new category to the list of British Regiment categories at https://www.wikitree.com/wiki/Category:British_Army.
It was a regiment that came and went, the first time when Napoleon was ensconced on the island, and later in 1842 when ... I have no idea why.
In any event, my ancestor served for seven years or so on the island in this regiment, and there were others.
