I wish I had asked those questions when my older relatives were still around. We talked about the "old folks" a lot so I have a lot of family info. One thing this questions brought back was what my great grandmother told.... She said on the ship coming over they went three days ahead and two days back with all the storms they encountered. A lot of the passengers were sick all the way over. Gee, sounds like a great trip!! But I am sure glad they made the journey.
Good luck on your searching. Makes me think of doing the same thing...hum!!
