Just saw your query today. I can confirm from a a partial transcript of the People's Cemetery, Charlottetown PEI:
Charles A. Stewart 1854 - 1933
Catherine McCallum 1852 - 1918
found on the best site for all things Prince Edward Island-
The Island Register http://www.islandregister.com/
Should you need information on "any other history or family there" post your query on The Island Register Queries Page and you will likely get a response.
