Hello Mithril, (is your name connected with the rare silver?).
I looked at the photo, and though I have a few possible guesses, the truth is that fig leaf morphology is extremely variable, especially in a plant so young as this. But keep that tree and grow it well! (It may even be one of those on you wish list). When the tree is bigger and makes fruit, take photos of the ripe fruit (outside and sliced in half longitudinally), together with a mature "typical" leaf. It'll be some time before you can get a real ID, but some of the folks on this forum are very good at identification based on those sorts of pictures. (Also the "eye" on the unripe and the ripe fruit are good indicators... but ripe fruit is pretty essential for identification). Until then call it something like "xxx Unknown" (you get to choose the "xxx").
Welcome to the forum, and enjoy growing your trees.
