Marta DeVeaux (1912-????) seems to have disappeared from history (at least as the internet understands it), after her brief sojourn in Hollywood.
Even the AFI catalogue knows nothing about her, though IMDb lists (on what authority it is difficult to say) five screen appearances between 1930 and 1934. All uncredited, these include Laurel and Hardy’s Sons of the Desert (1933) and the MGM musical Hollywood Party.
