Over the past 3 years I have been searching for emigration details of two uncles (miners) who had seemed to 'disappear off the radar'. I had turned the Ellis Island site upside-down looking for them to no avail, but I had never given up hope that I would find something eventually.
Within 4 hours of searching this site I found them. The first out of Liverpool to Queenstown then Boston and the second out of Liverpool to Philadelphia - both heading for the same mining area in Michigan.
Lots of good additional info. on the manifests too.
Bless you for passing this on.
