Walter O'Reilley
From Memory Alpha, the free Star Trek reference
Walter O'Reilley was a Human who was kin to descendants of Clare Raymond.
O'Reilley's name was read out in a computer display of the Raymond family's geneology, along with others such as Charles E. Winchester, Sherman T. Potter, Frances J. Mulcahey, and Margaret Houlihan. (TNG: "The Neutral Zone")
O'Reilley and others in the list seem to be references to characters in M*A*S*H productions.
