Hi Carina,
I tried to find some information about your Lars Larsen at the National Archives in Washington, D.C., last week, but I am disappointed. Here is what I did:
1) I sent email to the National Archives branch in New York City to ask if they have seamen's protection certificates (SPCs) for the port of New York for 1849. They said those records have been moved to Washington, D.C. They do have naturalization records from New York City and an index for those records, and they will do a search and send photocopies, but I think there is a charge of either $10 or $17.50.
2) I went to the National Archives in Washington and asked an archivist about the seamen's protection certificates. I took a copy of the image you posted on Hjælp til tydning so he could see the original certificate. He showed me a new microfilm number M2003 of "Quarterly Abstracts of Seamen's Protection Certificates for the Port of New York, 1814-1869." These are lists of SPCs issued for New York, showing the date issued, a file number, name of sailor, age, height, complexion, and birth place. For each 3-month period of every year, names are written with all the surnames starting with A first, then B-surnames, etc. If you find someone in the list, you can then request his file number to get more information. However, I looked at all of 1849 and 1850 for your Lars Larsen/Larson and did not find him, and I did not see any foreigners listed. I still think the original document you have shows that Lars Larsen was getting a SPC, and I am disappointed that I couldn't find proof of that in the abstracts on microfilm.
3) I posted a message on a mailing list for professional genealogists, asking if anyone knew what else could be done, and only received 2 replies: check Mystic Seaport web site [
library.mysticseaport.org] and look for New York crew lists.
4) At the Mystic Seaport web site, I did find some examples of SPCs [
library.mysticseaport.org] and a database of SPCs issued in Massachusetts [
library.mysticseaport.org]. You might want to send them an email, with a link to the image still on Hjælp til tydning, and ask if they have any information. They charge a fee to do research.
5) I will ask about New York crew lists on my next visit to the National Archives. I don't see any crew lists for New York from 1849 listed on the National Archives web site [
www.nara.gov].
Do you have any more information about the Mexican brig Montezuma that your Lars Larsen sailed on? Was it a passenger ship, or a cargo ship? I found a ship called Montezuma in the database of ships bringing Irish immigrants to the U.S., 1846-1851, and wonder if that could be it? I tried searching the Internet for Mexican brig Montezuma, got a lot of hits, but don't know which, if any, are the correct ship.
Maybe I can learn more on my next visit to the National Archives.
Mange hilsner.
