Dotsie,
I love the resolution. The Mormons have the best Geneology sites from what I hear. They do this as part of their Church. Before computers some of us visited the part of their church where they would help you with your Geneology.
Now the computer has sites for this too.
I am thinking about your aunts recollections and perhaps you could find the dates by typing in the name and ship. Not sure because I haven't tried it. My cousins daughter plans to type in the names of our grandfather and great uncle, the ship they came over on and hopefully will find them.
Thanks,
Maggie
