Query: Characterization of quadratic Cauchy-Stieltjes Kernel families by
  orthogonality of polynomials   In this paper we specify some facts about the sequence of polynomials
associated to a \CSK family and we prove that quadratic variance function is
characterized by the property of orthogonality of these polynomials.
