Ahearn Avenue was named after Thomas Ahearn . Born in LeBreton Flats in June 1855, Thomas Ahearn was the son of an Irish blacksmith on the Rideau Canal maintenance crew. At age 14 or 15 (reports vary), Ahearn got his first job in a branch telegraph office tucked away in the mills near his home. He worked for barter, running messages in exchange for lessons in keying. He became an operator and worked in the telegraph office at the House of Commons, sending parliamentary decisions down the wire to their relevant victims.
