  Generalized Stieltjes constants $\gamma$ n (a) are the coecients in the
Laurent series for the Hurwitz-zeta function $\zeta$(s, a) at the pole s = 1.
Many authors proved formulas for these constants. In this paper, using a
recurrence between ($\zeta$(s + j, a)) j and proved by the author, we prove a
general result which contains some of these formulas as particular cases.
