What is in This Collection?
The collection consists of a name index and images of the Merchant Seamen schedules from the 1930 U.S. federal census. The index is provided by Ancestry.com and corresponds to NARA publication: M1932: 1930 Census of Merchant Seamen.

The schedules consist of large sheets with rows and columns.

The following chart lists states with registered vessels which are listed in this census:

Federal census takers were asked to record information about all those who were on a vessel on the census day, which was April 1 for this census. The completed forms were then sent to the Census Office of the Commerce Department in Washington, D.C.

This information pertains to individuals and crew members of vessels on April 1, 1930.

The U.S. federal census has been taken at the beginning of every decade, beginning in 1790, to apportion the number of representatives a state could send to the House of Representatives. In the absence of a national system of vital registration, many vital statistics and personal questions were asked to provide a statistical profile of the nation and its states.

Federal censuses are usually reliable, depending on the knowledge of the informant and the care taken by the census enumerator. Some information may have been incorrect or deliberately falsified.

I Found the Person I Was Looking For, What Now?

 * Use the age listed to determine an approximate birth date. This date along with the place of birth can help you find a birth record. Birth records often list biographical and marital details about the parents and close relatives other than the immediate family
 * Use the race information to find records related to that ethnicity such as records of the Freedman’s Bureau or Indian censuses
 * Use the naturalization information to find their naturalization papers in the county court records. It can also help you locate immigration records such as a passenger list which would usually be kept records at the port of entry into the United States

I Can't Find the Person I'm Looking For, What Now?

 * Look for variant spellings of the names. You should also look for nicknames and abbreviated names
 * Look for another index. Local genealogical and historical societies often have indexes to local records

 * Try alternative search methods such as only filling in the surname search box (or the given name search box) on the landing page leaving the other box empty and then click on search. This should return a list of everyone with that particular name. You could then browse the list for individuals that may be your ancestor
