So far, we only know a few facts about the life of Alexander. 

Bathurst Courier, September 16,1853
Married, at Smiths Falls, on the 5th inst. by the Rev. Mr. Millen, Mr. Alex Weeks to Miss Isabella (Smith), daughter of Mr. Ralph Smith, both of North Elmsley.

The 1871 census lists an Albert and Isabella, who's ages and occupations match Alexander and Isabella. These two do not appear in the 1881 census for any of the surrounding townships, so either left the region or passed away. If Albert really is Alexander, he had died in 1880, so could be a fit for this confusion. It is reasonable to assume that Alexander and "Albert" are one and the same.
N. Elmsley 1871
Albert Weekes, age 46, born Ontario, Church of Scotland, origin Irish, Hotel Keeper
Isabella Weekes, age 34, born Ireland, church FRC (sic), origin Irish, Spouse
