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, an d 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.
