Lord Hemingford married Mary, daughter of
Valentine Graeme Bell, on 9 June 1902. Between 1918 and 1943, Herbert lived in a
Victorian villa at 36 Clarendon Road, Watford. This
locally listed building was later used as a
registry office until it was demolished in 2015 by
Hertfordshire County Council to make way for a
block of flats and offices. He died in December 1947, aged 78, and was succeeded in the barony by his son
Dennis Herbert. Lady Hemingford died in 1966. A 1944 portrait of Herbert by the Scottish painter
George Harcourt hangs in the
Watford Museum, and there are also photographic portraits of Herbert by the high-society portrait photographers
Bassano & Vandyk in the collection of the
National Portrait Gallery in London. ==References==
