The Sims family collection encompasses records of the Sims and Cook, Davidson and Garden families retained by members of the two family branches that came together when Harvey James Sims and Florence Katherine Roos married in 1902. Their Sims and Davidson forbears were equally significant in the history of the Waterloo-Wellington area and in the growth and development of agriculture, education, business and government. Harvey James Sims and Florence Katherine Roos were deeply involved in their local community of Berlin, (later Kitchener) Ontario and their own records contain significant additions to our knowledge of local personalities and affairs. Harvey was a childhood and lifelong friend of William Lyon Mackenzie King; they wrote and visited each other regularly. King's sister Bella was also a close friend of Florence from school days on.
