Do you recognize the names of these canal workers?

We have been writing about the Irish and Scottish settlers who came to Dartmouth in the mid to late 1820s to work on the Canal.  Our hope is that someone will recognize a name.    Recently archaeologists from Industrial Heritage Nova Scotia have invited the public to join them in the excavation of the remains of a bunkhouse, in Shubie Park, where Canal workers may have stayed.   Perhaps one of the following might have lived in this dwelling – Timothy Horan, John and James Marra (Blacksmiths) and William Quinn.  Do any of these names ring a bell – might one be a relative of yours?
