intermarriages between voc employees and locals were encouraged, which led to the creation of communities of dutch descendants. today, there are only five surviving coherent and large communities who are descended from those early intermarriages. they are the cape coloureds (south africa), basters and oorlam (namibia), burghers (sri lanka), and indos (indonesia). other dutch groups have persisted as a strain among the anglo-burmese and kristang. the dutch eurasians of malacca are of dutch and largely malay but also indian or chinese descent. the dutch transferred malacca to the british in 1825 in exchange for territory in sumatra. the british sought to depopulate malacca and as a result many eurasians and other people moved north to thriving penang (where other eurasians fleeing phuket or moving from kedah also settled) and later south to singapore as it grew in the late 19th and early 20th centuries. dutch descendants in malaysia and singapore are primarily made up of eurasians originating from malacca, as well as others who emigrated from the east indies, india and sri lanka. leo and hilda campbell were dutch burghers who arrived in singapore from sri lanka (then ceylon) in 1910. the couple planned to migrate to australia like many eurasians but due to hilda suffering a stroke, they remained in singapore.
