  Using an $SO(10)$-inspired form for the Dirac neutrino mass, we map the
neutrino data to right-handed neutrino Majorana mass-matrix, $\mathcal M$, and
investigate a special form with \emph{seesaw} tribimaximal mixing; it predicts
a normal hierarchy, and the values of the light neutrino masses. It may be
generated by mapping the top quark hierarchy onto the vacuum values of familon
fields transforming under the family group $\mathcal{ PSL}_2(7)$. We next
investigate the hypothesis that these familons play a dual role, generating a
hierarchy in the supersymmetric $\mathbf \mu$-mass matrix of Higgses carrying
family quantum numbers. A special $\mathcal{ PSL}_2(7)$ invariant coupling
produces a $\mu$-matrix with a hierarchy of thirteen orders of magnitude. Only
one Higgs field (per hypercharge sector) is light enough (with a $\mu$-mass
$\sim 10-100$ GeV) to be destabilized by SUSY soft breaking at the TeV scale,
and upon spontaneous symmetry breaking, gives \emph{tree-level} masses for the
heaviest family.
