Was Joseph Smith interested in and familiar with Kabbalah?

We know that historically Joseph Smith taught himself Hebrew (as to how well, I'm not sure), and that he held beliefs similar to Jewish mysticism (degrees of heaven, preexistence, fall of angels, etc.), but do we know if he had access to and was familiar with Kabbalah writings? Did he study them in the original Hebrew? How familiar would the average American Christian leader at that time be with Kabbalah? Is Joseph Smith exceptional in this regard?
