Hello Jan...
Siwash was a word used in the distant past. It was a word from the Hudson Bay Co. Chinook Jargon (not an official language) that was used for trade in the Colonial Period of BC history and survived to a time shortly after the turn of the 20th Century.
http://tenaswawa.home.attbi.com/gibbs.htm ..... Today you will find words to describe the people who fall into the terrirory of the South Western portion of BC using the name Salish, and Coast Salish but it too does not sufficiently describe correct names for the First Nation people who live here. Today, the term for the people who live along the lower Fraser River to the south and east portion of Vancouver Island is Halkomelem. Halkomelem (properly written Halq'eméylem) is a Salish language spoken in British Columbia, around the Fraser river and in the southern end of Vancouver Island. There are three dialects, Halq'eméylem, spoken by the upriver Stó:lo or Fraser people; Hun'qumi'num' dialect of the downriver Stó:lo; and Hul'q'umÃn'um' dialect spoken in Vancouver Island by the following peoples: Nanoose, Nanaimo, Chemainus, Cowichan, and Malahat. Etnographic words class these peoples with the label "Central Coast Salish", but there are many other groups under the same label, speaking different languages.

You may wish to find out what part of the Hulkomelem territory August Jack came from... it is a rather large area (Hope to South East Vancouver Island & Gulf islands). This would be the best place to start. Be careful not to assume that August stayed in one area if he was living before Reservations were placed upon his freedom. As his territory would have been extensive for hunting and fishing and seasonal homes. Also after Missionary and Colonial contact August may have been forced by law into a residential school if he was of age, when that paternalistic law was in effect (1870's up to the 1980's). So that may have meant that he (as a child) was pulled from his family in his traditional home to be placed hundreds of miles away... Kamloops, Lytton, and Kuper Island are sites of some of the 14 Residential schools throughout BC. Thousands of children were taken from family to be placed in residence many miles away from home and family. Many of these children grew up only to find themselves disconnected from their heritage and family so they chose to make a life in the area of the residential school and married into Reserves other than their own. So be aware that August could very well have been from the lower Fraser River and have been forced to Kamloops only to chose to stay in his new home as an adult....(that is just an example)... it may not be the case for August Jack.

I have no idea who August Jack was but I wish you all the best in your research. If you find that one of the above names is your relation the actual certificate can be purchased from the Archives on line. The actual paper would hopefully give more details such as parents names and witnesses and birthplaces.
Good luck and best wishes.... Rocky Sampson
