Is there evidence of a moon orbiting a moon orbiting a planet?

Has there ever been evidence of a smaller object orbiting the moon of a planet?

No, but there is a moon that has smaller Trojan moons, that orbit 60 degrees ahead or behind its orbit due to the mutual influence of Saturn and the big moon. The big moon is Tethys, the small moons are Telesto and Calypso.

There are smaller objects orbiting our moon, but these are man-made.
