Those of us who research NYC know that the city has been putting birth certificates, marriage certificates, and death certificates online.

What I did not realize is that marriage licenses are online too.

I knew my father-in-law and his first wife had marriage certificate #9090 in a certain year and borough. When I searched the city site by certificate number, it pulled up their certificate, but it also showed a marriage license for a different couple with the same number.

So I went to Ancestry’s New York City Marriage License Indexes, found my father-in-law’s actual marriage license number — 9016 — and searched that number back on the city website.

There it was: their marriage license.

Made my Saturday night!

And yes, if I had kept up with the city’s digitization updates, I would have known this.)
