Have you tried looking into the Ellis Island records for your Great Grandfather? https://heritage.statueofliberty.org/

I was able to find some of my ancestors who came to the US from those records. People usually came by ship and New York City was one of the main points of entries to the US.

Thanks for the tip! I just tried it quickly, but will need to try many more combinations. The last name of my Great Grandfather is Khouri, which means Priest, and is very, very common. However, when we found his record in 1925 in Canada, it was spelled "Elkhoui". Note the missing 'r', and they attached "El" to it.

So as you can see, I would never have guessed it, and we found it by manually searching by timeline for anyone from "Lebanon", or "Syria", or even "Turkey", as data entry was usually done by just a person that may have never heard of that language, and just "guessed". Remember, IDs are a modern invention, so back then, it was not standardized.
