Finding passengers on ships lists to Baltimore Maryland

There are 2 separate indexes for Baltimore for the years 1833-1866. One lists passengers on federal lists, the second lists passengers on city lists. You can't just check one - if you check one and don't find your ancestor, you have to
check the other one.
