I found a most unusual certificate yesterday.
A good amount of my genealogy research in the US is attempting to find the origin location of immigrants. One of the best documents for doing this is naturalization records. It’s best if they naturalized after 1906 when the federal government standardized the forms, providing much more information.
Many of the documents I see contain a certificate of arrival along with the declaration and petition. Someone had to look through the ship lists and find the immigrant’s arrival. They marked the original ship list page and filled in a certificate saying they found it, the name the person arrived under, the ship, date, and port.
But yesterday, I found something new. It was a certificate of arrival that said a record of his arrival couldn’t be found. This was a first for me.

Also of interest, the Declaration listed the same ship as his wife’s naturalization years later. (She had no certificate of arrival and I haven’t found her on the ship either.) The Petition listed “SS Unknown”.
An additional detail: he was about 21 years old for his arrival. So it’s not like he arrived as an infant and had no memory of the event. And his naturalization was in 1924.
The next question is, can I find the ship list that the immigration authorities couldn’t find when the guy was alive? Well… I may have already found it. It needs more research to verify if it’s really him.
