What is "coelerni"

The Coelerni were an ancient Celtic tribe of Gallaecia in Hispania (the Iberian Peninsula), part of Calaician or Gallaeci people, living in what was to become the Roman Province of Hispania Citerior, convent of Bracara Augusta (the modern Portuguese city of Braga), in what is now the southern part of the province of Ourense (in Galicia).

Some sources, like Alarcão, also state that the Coelerni lived in the north of modern Portugal, in the province of Trás-os-Montes, in the mountains between the rivers Tua and Sabor - this seems to be incorrect and predates the finding of the Tessera Hospitalis of Castromao. However there was a lusitanian people of the Colarni (inscription of Alcantara) living near the Douro river in Lamego, that could have some link with the galician Coelerni.
