August Jack (Khatsahlano, Xats'alanexw) (July 16, 1877 – June 5, 1971) was an Indigenous/Aboriginal chief of the Squamish people. He was born in the village of Xwayxway on the peninsula that is now Stanley Park, Vancouver, or at Chaythoos, British Columbia, Canada and the son of Supple Jack “Khay- Tulk” of Chaythoos and Sally “Owhaywat” from the Yekwaupsum Reserve north of Squamish, British Columbia. His grandfather was Chief Khahtsahlano of Senakw (aka Snauq or Sun'ahk) who had migrated from his home at Toktakanmic on the Squamish River to Chaythoos, and the man from whom he inherited his name. The suffix “lan-ogh” in their name means “man”.
August Jack’s father died the day he was born, and his mother remarried Shinatset (Jericho Charlie). One day soon after Supple Jack’s burial at Chaythoos, city surveyors unexpectedly started chopping down his family's house while they were inside. They were to build a road around the area, naming it Park Road. As August Jack recalls in his conversations with J. S. Matthews, the road around the park “did not touch my father’s grave, so they left it there, but when it came we had to move away. We had to move out of the house and they tore it down, but they left the grave for a long time, until after Lord Stanley named the park Stanley Park. Then they took the coffin up to Squamish” August Jack’s family home and village were destroyed, and himself and the other members of the community were relocated to Snauq, the area under the southern end of the Burrard Bridge at the mouth of False Creek, while some people went to live on the reserve at Kitsilano Point. He lived in the village of Snauq for most of his early life, working at a sawmill nearby. At this Squamish village around 1900, in a ceremony attended by visiting people from Musqueam, Nanaimo, Sechelt, and Ustlawn (North Vancouver) his grandfather’s name was given to him as his own. In this same ceremony, his brother Willie was named Khay-Tulk after his father. August Jack gave a potlatch and feast for the guests in attendance and distributed over one hundred blankets to them.
