We find three shallow bound states for the NNN$\\Xi$ system (with $(J^\\pi,T)=(1^+,0)$, $(0^+,1)$ and $(1^+,1)$) with quite similar binding energies. The $^5_{\\Xi}\\mathrm{H}(\\frac{1}{2}^+,\\frac{1}{2})$ and $^7_{\\Xi}\\mathrm{H}(\\frac{1}{2}^+,\\frac{3}{2})$ hypernuclei are also clearly bound with respect to the thresholds $^4\\mathrm{He} + \\Xi$ and $^6\\mathrm{He} +\\Xi$, respectively.
