The original inhabitants of the area were the people of the Ben Lomond Nation, which consisted of at least three clans totalling 150-200 people. Three clan names are known but their locations are somewhat conjectural - the clans were recorded as Plangermaireener, Plindermairhemener and Tonenerweenerlarmenne. The Plangermaireener clan is recorded as variously inhabiting the south-east aspect of the Ben Lomond region and also has been associated with the coastal tribes to the south-east.: This clan was likely to have occupied the region of the modern day Fingal Valley to the St Mary's Plains and east coast region. 'Plangermaireener' is also used as a blanket term for all the members of the Ben Lomond Nation which reflects the suffix 'mairener', recorded as meaning 'people' or 'tribe'.:
