The Langford Rae family that is, a family called Rae among whom "Langford" repeatedly appears as a first or middle name originated in southern Ireland: there are numerous references to the name in Irish records, nearly all clearly associated with the area of County Kerry on or near the Dingle Peninsula, or with neighbouring areas of County Limerick. It is difficult to sort out their exact relationships, since so many of the Irish geneaology records were destroyed in The Troubles, but the fact that the family were significant landowners means that there is more information available for them than for most Irish families of the period. NUI Galway's Landed Estates section records that "Members of the Rae family, whose estate was centred on Keel House, Castlemaine, held over 5000 acres in county Kerry in the 1870s".
