  We report the crystal field levels of several newly-discovered rare-earth
kagome compounds: $\rm{Nd_3Sb_3Mg_2O_{14}}$, $\rm{Nd_3Sb_3Zn_2O_{14}}$, and
$\rm{Pr_3Sb_3Mg_2O_{14}}$. We determine the CEF Hamiltonian by fitting to
neutron scattering data using a point-charge Hamiltonian as an intermediate
fitting step. The fitted Hamiltonians accurately reproduce bulk susceptibility
measurements, and the results indicate easy-axis ground state doublets for
$\rm{Nd_3Sb_3Mg_2O_{14}}$ and $\rm{Nd_3Sb_3Zn_2O_{14}}$, and a singlet ground
state for $\rm{Pr_3Sb_3Mg_2O_{14}}$. These results provide the groundwork for
future investigations of these compounds and a template for CEF analysis of
other low-symmetry materials.
