For those of you who had Irish ancestors who you know left Ireland and were perhaps likely to be heading for Canada, and then just seem to vanish, this site may be worth checking: Grosse Île Quarantine station. A very sad end to what must have been a desperate and difficult journey.

Best wishesIf some of your ancestors passed away at the quarantine station at Grosse-Île, their names might appear on the memorial erected by Parks Canada in 1998. This monument was placed close to the western cemetery, and bears the names of people who died either on Grosse-Île or on the boats: immigrants, employees and sailors. Of the 7553 people buried here, 1545 are still unknown. ....only the names of the deceased are on this list.
