Not such a tall order after all. Here are several options.
I made a search of the subscription website Ancestry.com (www.ancestry.com), a website commonly used for genealogical research. Ancestry has databases of the names of passengers aboard ships arriving at certain U.S. ports of entry from a foreign country. So I searched simply for "Falcon" for March 1947 and found the passenger list in question. (MARINE FALCON departed Southampton, England, on March 12, 1947. She made stops to pick up additional passengers in Le Havre, France, and Cobh (Cork), Ireland, before reaching New York City on March 25, 1947. Her manifest lists 1,072 passengers.) Ancestry gives you a variety of ways to search its files. Presumably you are searching for an individual or a family and you can search by an individual's name for a specific date of arrival, and print the information from the screen. While Ancestry is a subscription website, you can sign up for a 14-day free trial, make your search(es), cancel your membership within 14 days and owe nothing. You can also obtain ongoing memberships beginning at $20 per month and up depending on what type of subscription you want.
Passenger records include: name, age, gender, marital status, occupation, whether able to read and write and if so in what language(s), nationality, race, birthplace by country and city, passport or visa number and where and when same was issued, last permanent residence by country and city, name and address of nearest relative or friend in the originating country, final destination by country, city and state (if in U.S.), who paid for passage, whether the person in had ever been in the U.S. before and if so when and where, whether planning to meet a relative or friend at their destination and if so who, relationship and address, purpose of coming to the U.S., state of physical and mental health, if deformed or crippled the nature of same, height, complexion, color of hair and eyes, and identifying marks. Wow. If a family was traveling together, all members are listed consecutively.
Second option: if you wish to identify the person or persons in which you are interested, I'll look up the information for you and forward it to you.
Another option: the same ship manifest is available on the free website www.ellisisland.org. You can search only by the name of an arriving passenger/immigrant but it brings up the same information either as a very brief summary for the passenger or the full manifest record. You can either print from the screen or purchase a print of the microfilm images of the full manifest record (which runs two pages), $30 for one page and $20 for the second page. You have to create an account to search the site but the account is free.
Another option is to use the search site www.familysearch.com, which is affiliated with the Mormon church. You need an account (also free) to
search. I do not have an account and am too lazy right now to create one so I cannot verify whether the MARINE FALCON passenger manifest is available.
Anyway, you have options. Good luck.
