Edward Boustead

Boustead had a daughter, Helen Boustead, who was born in 1857. Helen Boustead married William Niven and the couple gave birth to a son, William Edward Graham Niven.

William Edward Graham Niven then married socialite Henrietta Julia Degacher. Their first child was James David Graham Niven, better known as David Niven. Niven's film career spanned over 90 films, and he was best known for his roles in Around the World in 80 Days (1956), The Pink Panther (1963) and Casino Royale (1967). There has been some dispute over Niven's paternity, with one biographer claiming that Niven himself believed his biological father to be Sir Thomas Comyn-Platt, whom his mother later remarried after her first husband was killed on active service in 1915.

Many sailors were left homeless when they were sick or too old to work. Boustead was an altruistic man and he felt compassion for these sailors. He built the Boustead Institute, situated at Tanjong Pagar. The building came to be known as the Sailor's Home, providing accommodation for sailors of ships visiting the port as well.

Boustead also donated charitably to hospitals, schools and churches. Some of these buildings included Raffles Institution, Saint Joseph's Institution and the Cathedral of the Good Shepherd.

In 2014 Boustead & Co co-founded Noble Tree Property Investment, a socially minded property company that develops, owns, lets and sells affordable housing and specialty supported housing developments across the United Kingdom.

In 2015 Boustead & Co founded Boustead Asset Management Limited in Mauritius to serve as the investment advisor to Boustead Investment Fund, a social impact investment fund with a focus on investing in socially conscious investments. The asset manager and fund are regulated by the Financial Services Commission in Mauritius and were granted a Collective Investment Scheme Manager Licence and Category 1 Global Business Licence by the Financial Services Commission.
