Gail Dever drew my attention to a recently launched virtual archive of famine stories at the University of Limerick.
"The archive translates the French language annals and pays tribute to the French-Canadian Sisters of Charity, or Grey Nuns, who cared for the Irish Famine emigrants in the fever sheds of Montreal during the summer of 1847 and provided homes for Irish widows and orphans. These annals contain extensive and highly evocative eyewitness accounts of the suffering of famine migrants in 1847."
There are many names of those involved, and those who died, in providing the service in the fever sheds. Don't expect to find immigrant ancestor's names. Included is a brief mention of the situation in Bytown.
You may also be interested in other University of Limerick History of Family projects documented at the website.
Thanks to Gail for the tip.
