The Codex de Roda names "domna Lopa" as the child of "Sanzio Garseanis…ex anzilla", stating that she was mother of "Regemundo de Bigorra". She was probably much older than her legitimate brother and sisters, her husband being the great-uncle of the second husband of her half-sister Velasquita Sánchez. 1
