The anthropologist Viola Garfield wrote in 1938 that the then-current head chief of the Ginadoiks, Cecil Ross, Niisweexs ("Grandfather of Weexs"), had come from the Tsimshian community of Kitkatla three generations earlier "when his 'brother' usurped his place and took the ... chieftainship" of the Kitkatla tribe.
The leading, royal house of the Ginadoiks had become extinct, allowing the Kitkatla man to accede to the name Niisweexs.
One of these last two Niisweexses was Henry Nelson, who died in 1925 and whose mortuary rites are described in detail in Garfield's monograph.
He was a shaman whose fame had spread as far as the Nass River, his supernatural gifts having been evident at his birth since he had been born with a caul.
Since he had no matrilineal heirs, shortly before his death he adopted his own wife into his house-group as his sister so that she could inherit the prerogatives of the House of Niisganaas.
