  Following the recent realization of an artificial version of Graphene in the
electronic surface states of copper with judiciously placed carbon monoxide
molecules inducing the honeycomb lattice symmetry (K. K. Gomes et al., Nature
483, 306 (2012)), we demonstrate that these can be used to realize a vortex in
a Kekule texture of the honeycomb lattice. The Kekule texture is mathematically
analogous to a superconducting order parameter, opening a spectral gap in the
massless Dirac point spectrum of the Graphene structure. The core of a vortex
in the texture order parameter, supports subgap states, which for this system
are analogs of Majorana fermions in some superconducting states. In particular,
the electron charge bound to a single vortex core is effectively fractionalized
to a charge of $e/2$. The Kekule texture as realized in the molecular Graphene
system realizes 3 different domain types, and we show that a Y-junction between
them realizes the coveted Kekule vortex.
