  CeRh$_6$Ge$_4$ is unusual in that its ferromagnetic transition can be
suppressed continuously to zero temperature, i.e., to a ferromagnetic
quantum-critical point (QCP), through the application of modest hydrostatic
pressure. This discovery has raised the possibility that the ferromagnetic QCP
may be of the Kondo-breakdown type characterized by a jump in Fermi volume, to
which thermopower S measurements should be sensitive. Though $S/T$ changes both
sign and magnitude around the critical pressure P$_{c}\approx{}0.8$ GPa, these
changes are not abrupt but extend over a pressure interval from within the
ferromagnetic state up to P$_c$. Together with temperature and pressure
variations in electrical resistivity and previously reported heat capacity,
thermopower results point to the near coincidence of two sequential effects
near P$_c$, delocalization of 4f degrees-of-freedom through orbital-selective
hybridization followed by quantum criticality of itinerant ferromagnetism.
