Luis de Bigorre was born on an unknown date to Ramon I Donat de Bigorre (c910-?) and Tachilène of Astarac (c920-c967) and died 1000 of unspecified causes. Notable ancestors include Charlemagne (747-814). Ancestors are from Germany, France, Belgium.
Luis was Count of Bigorre. He seems to have had no adult children, as his nephew inherited the county.
