Abstract
In this article, we present a class of identities linking together Cauchy numbers, the special values of the Riemann zeta function and its derivative, and a generalization of the Roman harmonic numbers, which represents a significant refinement and improvement of our earlier work on the subject.

Notes
If \(b(n) = \frac{1}{n} \sum _{j=1}^n (-1)^{j-1} \left( {\begin{array}{c}n\\ j\end{array}}\right) j\,a(j)\), then \(a(n) = \frac{1}{n} \sum _{j=1}^n (-1)^{j-1} \left( {\begin{array}{c}n\\ j\end{array}}\right) j \, b(j)\) (cf. [5, Definition 5 and Corollary 1]).
