The ancestral seat of the Barons de Freyne was the French Park Estate, County Roscommon. The manor house, originally built in the mid-17th century before being rebuilt in the Georgian style in the 18th century was demolished after the sale of the estate by the 7th Baron de Freyne to the Irish Land Commission in 1952. The Land Commission removed the roof of the buildings in 1953 and eventually demolished the remaining structures in ca 1975. The present Lord de Freyne lives with his wife and family at Putney in the London Borough of Wandsworth.
