Genealogical research on the Lugones draws on documentary sources from Spain, Argentina, Bolivia and Peru, spanning colonial, civil and ecclesiastical archives of several centuries.
The geographic spread of the sources mirrors the history of the surname itself: born in Spain, transplanted to the Viceroyalty of Peru and settled in Argentina.
Some documents are especially valuable for the amount of information they provide about the Lugones family.

Parish records —baptism, marriage and death certificates— are an indispensable source for reconstructing genealogies prior to the civil censuses. In the research on the Lugones, these documents make it possible to trace branches of the family back to the 17th century.
The archives consulted include parishes and dioceses of Santiago del Estero, Córdoba, Buenos Aires and other provinces, as well as the microfilms made by the Church of Jesus Christ of Latter-day Saints (Mormons), which digitized a significant portion of the Argentine ecclesiastical records.
