Bennelong was a member of the Wangal clan who lived on the south side of Parramatta River. He had close links with the Wallumedegal clan who lived on the west side of the river, and the Burramattagal clan who lived near today's Parramatta. He had several sisters, including Warreeweer and Carangarang, who married important men from other clans. This gave Bennelong strong political links to the clans living around the new settlement at Sydney. Bennelong had a daughter named Dilboong who died as a baby, and a son who was adopted by Rev. William Walker. Named as Thomas Walker Coke, he died after a short illness aged about 20.
