Welcome to RTHS
The Rideau Township Historical Society (RTHS) was formed in 1974, the same year the historic townships of North Gower and Marlborough were joined to form Rideau Township. The RTHS mission is to "preserve the past to enrich the future" by increasing awareness of and access to the history of the former Rideau Township, which was amalgamated into the City of Ottawa in 2001.
The symbols in the RTHS crest (see above) reflect the pursuits of the early settlers in the area. As illustrated in the images at right, river transport and commerce, forestry, agriculture and livestock were the essential ingredients that enabled the founding townships of North Gower and Marlborough to realize Peace, Plenty and Progress.

Presenter: Alison Cheng. Article and Pictures by Lucy Martin. February, 2015.
The speaker, Alison Cheng, was a 3rd year co-op student at the University of Ottawa. She was pursuing an honours bachelor of arts degree, majoring in history with a minor in social sciences of health. In the summer of 2014, Cheng spent a work term conducting research for RTHS’s Dickinson House committee. The purpose was to examine connections (real or presumed) between Sir John A. Macdonald, Manotick and the family of Moss Kent Dickinson.
Cheng scoured primary and secondary sources seeking evidence that bolstered or debunked an oft-repeated claim that Dickinson House had been an unofficial headquarters for Macdonald campaigns.
Cheng’s conclusion? Very likely that was not the case.
But first, a little chronology. Conservative politician Sir John Alexander Macdonald (1815-1891) was Canada’s first Prime Minister. He held that position twice, across different decades: 1867-73 and again from 1878 – 1891. (He died in office.)
Dickinson House was built in 1867 by Moss Kent Dickinson. He moved there as a widower with 5 children in 1870. Dickinson had been the mayor of Ottawa (1864-66) and was elected as a Conservative MP from Russell from 1882-87.
Cheng took us through the complexities of the separate elections for both men, including the personalities and politics of their opponents.
