A couple also may not marry a member of another lakinyeri if they have a great-grandparent (or closer relation) in common. Norman Tindale's research in the 1920s and Ronald and Catherine Berndt's ethnographic study, which was conducted in the 1930s, established only 10 lakinyerar. Tindale worked with Clarence Long (a Tangani man) while the Berndts worked with Albert Karloan (a Yaraldi man). Malganduwa – No references before Berndt. No family groups identified.

George Taplin recorded in 1879 that the Ramindjeri occupied the southern section of the coast from Encounter Bay, some 100 km south of Adelaide, to Cape Jervis but made no mention of any more northerly Ngarrindjeri occupation.
