"[4] The settlement's original was Cumbrocoa or Cumbrocobe, but it was changed to its current name in 1895 – when the Mayo River dried up, the natives noticed snakes in the puddles left behind.

[5] In 1920, the brothers decided to split up their land: Ildefonso and Epifanio got their part in Bacobampo while José María went to Basconcobe [es].
