Currently, the presence of Occitan (Pyrenean Gascon, in particular) in Spain is in the comarca of Aran Valley in Catalonia. But in the past, Occitan was spoken in other parts of present-day Spain, especially in parts of the Crown of Aragon and Kingdom of Navarra; in fact, two important documents related to the history of Jaca was mostly written in Occitan. In fact, it was said that the speech spoken in Upper Aragon today have a significant Occitan influence due to its location.
Personally, Occitan (or more specifically, Pyrenean Gascon) speakers in the north of present-day Aragonese territory could spread their language southward as Crown of Aragon annexed new lands as part of Reconquista. However, it's also understandable somehow that the Occitans in the rest of Aragon (especially in Huesca and Zaragoza) was quite small and quickly assimilated to the rest of the population, who spoke variants of Navarro-Aragonese (or Aragonese, for short) language.
With a PoD of 13th century and earlier, make Occitan (more specifically, Pyrenean Gascon) having a significant foothold in Spain, most especially in the north.
