Perhaps two-thirds of the pioneers have been identified and placed in their travel companies, but thousands remain to be found, usually one traveler or one family at a time. Whenever I run across a reference to the date someone arrived in Utah, I’m in the habit of checking the database to be sure they are listed. Usually they are. But when they are not, I always spend a few minutes or a few hours finding sufficient information to list them. Some people like crosswords or soduku; I like solving the puzzles of the pioneers.
