Integrals involving the kernel function $sech (\pi x)$ over a semi-infinite range are of general interest in the study of Riemann's function $\zeta(s)$ and Hurwitz' function $\zeta(s,a)$. Such integrals that include the $arctan$ and $log$ functions in the integrand are evaluated here in terms of $\zeta(s,a)$, thereby adding some new members to a known family of related integrals. A claimed connection between $\zeta(s)$ of odd integer argument and such integrals is verified.
