Dunbarton is situated on land first settled by the Linton family from Scotland in 1894. Sister Mary Baptista, Order of Visitation (formerly Sarah Eliot Linton), donated her family estate, Lintonsford, to the Benedictine Monks for the purpose of opening two schools to serve disadvantaged children. 

 

The land for Dunbarton was later sold to provide residential development.  On these 141 acres, where the Sisters once picked berries and fished, are now 479 homes.

 

The Broad Run Scenic Trail runs through Dunbarton offering pedestrian and bicycle trails that parallel the stream on one or both sides.
