Shanning might be a variation of
Channing (which is English and means "knowing"). It also could be Irish (since it's similar to
Shannon and Shanahan). From search results, Jarrick looks like it's a
German surname. As a first name, it could be a mixture of
Derek (or
Derrick) and
Jared combined or a variation of the Polish name
Jarek, which means "born in January". The last name Jarrick might also be a
German variation of
Jarek. I'm really not sure about that though.
