To be, or not to be...a Huguenot...that is the question

I have come to an impasse, until I can find more sources. Could the Rulong's descend from a Huguenot?

Ancestry.com

With possible name changes along the way how can I get concrete evidence that I am on the right track? I am certain of my pedigree back to Aaron Rulong (1768-1822) but then things get a little fuzzy. Based on some other trees the lineage looks like the above. My curiosity feels the need to dig deeper and verify this.

According to The Huguenots or early French in New Jersey, Ruel was the only protestant in his family and he was smuggled on to a ship bound for America.I am not sure how then someone with the same name appears on a ship manifest...unless that was the only way to get him past some type of security and he actually was named on the ship record? Big old mystery to me. Something I am looking forward to investigating!
