It’s possible he meant the Algiers in Louisiana, but what he has on his Facebook page is Algiers, Algeria.
In Louisiana, Algiers is the colloquial name for the fifth municipal district of the city of New Orleans, akin to one of the Paris arrondissements. It's not an "official" municipal name for a town or city in Louisiana, so I agree - the deceased was working with Facebook's limitations. He probably never had a clue as to what or where Algeria was.
