On the day of their arrival, the three 1904 passengers, Bronislawa, Frank, and Stella, were admitted to a quarantine station at Grosse Île, located on the St. Lawrence River near Québec. Stella was reported as having a fever. The three left the station thirteen days later, on July 9. The ship name and date of admission on all three of our immigrants' records match the ship name and date of arrival from the ship passenger list also presented here, as do of course their names and, for the most part, their ages. You can view transcriptions of the records as PDF's linked at the bottom of this page.
The records are from the hospital admission book, which has been transcribed into a digital database format in recent times for use as a historical and genealogical tool. It can now be searched online here. I am not aware of scanned images of the original documents being available on the internet currently.
The quarantine station closed in 1937 and is now a national historic site. Read more about the station here.
