A non-trivial supergeneralization of the Kerr-Newman solution is considered as representing a combined model of the Kerr-Newman spinning particle and superparticle. We show that the old problem of obtaining non-trivial super black hole solutions can be resolved in supergravity broken by the Goldstone fermion. Nonlinear realization of broken N = 2 supersymmetry specific for the Kerr geometry is considered, and some examples of the super-Kerr geometries generated by the Goldstone fermion are analysed. The resulting geometries acquire torsion, Rarita-Schwinger field and extra wave contributions to the metric and electromagnetic field caused by Grassmann variables. One family of the self-consistent super-Kerr-Newman solutions to broken N = 2 supergravity is selected, and peculiarities of these solutions are discussed. In particular, the appearance of extra `axial' singular line and travelling waves concentrated near `axial' and ring-like singularities.
