We present the masses of singly (B, Bs, Λb, Σb, etc.), doubly (Bc, ηb, Υ, Ξbc, Ξbb, etc.), and triply (Ωbcc, Ωbbc, Ωbbb, etc.) heavy hadrons arising from (QCDSF-UKQCD) lattices with improved clover-Wilson light quarks. For the bottom quark, we use an O(a,v4)-improved version of lattice NRQCD. Part of the bottomonia spectrum is used to provide an alternative scale and to determine the physical quark mass and radiative corrections used in the heavy-quark action. Results for spin splittings, opposite parities, and, in some cases, excited states are presented. Higher lying states and baryons with two light quarks appear to be especially affected by the relatively small volumes of this (initially) initial study. This and other systematics are briefly discussed.
