Family history

The prominence of the Barker-Mill family in Southampton is deep-rooted and recognised on the Bargate, the fortified Norman tower guarding the entrance to the city, where the Barker-Mill family shield still remains on display, alongside those of other great Southampton families.

The first John Mill left his mark as a merchant in Southampton’s thriving and cosmopolitan trading centre, circa 1504. By 1613 the family was well enough established to afford an impressive memorial in Nursling Church, Southampton.

In the 18th Century the family inherited Mottisfont Abbey near Romsey, where trees they planted still grow today.

1836 saw the first Barker-Mill. The Rev Sir John Barker-Mill was a jolly figure, famous for his loud check trousers and cherry-coloured ties.

Victorian matriarch Mrs Marianne Vaudrey Barker-Mill was the opposite of Rev Sir John. A good businesswoman, she pulled the Barker-Mill finances into shape, selling land at Millbrook, which grew into Southampton’s massive docks.

Another dynamic Barker-Mill businesswoman followed. Brenda Barker-Mill set up a chauffeur service for tourists after the Great War, taking travellers as far as Edinburgh in a second-hand Rolls Royce. Brenda’s son Peter was an artist but creating vast sculptures and illustrating books didn’t distract him from his local responsibilities.

Following Peter’s death in 1994, he is survived by his daughter Amanda, and son, Adam. Both Amanda and Adam are dedicated to the family and the estates.

Amanda launched Britain’s first Butterfly Farm in the New Forest in 1981 and developed Longdown Dairy Farm as a tourist attraction in 1985.

Adam works as a light artist, creating dramatic installations for exhibition.

Longdown Management

The Barker-Mill Estates are managed by Longdown Management Limited.

Formed in April 1977 the company’s principal function is to manage property belonging to the Barker-Mill family and its Trustees.

In total, Longdown Management handles approximately 2,000 acres of tenanted farmland and a similar acreage of land let on short term tenancies and licenses. It also manages an additional 1,500 acres of woodland, as well as lettings of sporting rights over some of the estates land, lettings of salmon, trout and other fishing on lakes and the southern part of the River Test below the M27 motorway and part of the Lymington River.

Other management includes lettings of mineral extraction and infilling rights. Lettings of over 150 residential properties situated between the Western boundary of Southampton and the Eastern side of the New Forest National Park, are also handled by Longdown Management, as well as the management of various commercial lettings.

Longdown Management is retained to manage land and property for other private and corporate owners.

The Barker-Mill family has deep roots in Hampshire, where they have been landowners for over 500 years.  The estates are now held principally by Trustees, whose purpose is to act as custodians.  The Trustees intend to protect and enhance the family’s success, heritage, and reputation, whilst respecting and working to contemporary values and acting in a responsible and sustainable fashion.

The Barker-Mill Estates aim to be financially independent, generating sufficient sustainable returns for their maintenance and re-investment, at an appropriate level of risk.
The Trustees manage the Estates’ portfolio of assets in a responsible but commercial fashion, also in the interests of present and future generations of the Barker-Mill family.
InclusivenessDecisions are taken after consultation with relevant stakeholders (including, as appropriate, beneficiaries, managing agents, professional advisers, tenants, employees and local stakeholders).
ProtectiveThe Trustees are conscious of the need for and desirability of sustainable management, including the provision of environmental benefits through such programmes as woodland creation schemes and solar energy generation.  They also look to support the local economy by utilising local trades and businesses.
The Trustees wish to act ethically and, in line with the Barker-Mill family’s own values and wishes, believe in giving back to the community.  The Barker-Mill Foundation, an independent charity funded from the family’s wider wealth, has supported local charities by gifting over £4 million since its inception in 1995.
Well-BeingThe Estate activity provides for and the Trustees wish to support the improvement of local health and well-being, for example, by providing land for the construction of the Marchwood to Eling cycle path as well as granting permitted footpaths through Estate woodlands in the Nursling and Rownhams area.
