We report Hall, magnetic, heat capacity and doping studies from single crystals of Yb₁4MnSb₁1 and Yb₁3.3La₀.7MnSb₁1. These heavily doped semiconducting compounds are ferromagnetic below 53 K and 39 K respectively. The renormalization of the carrier mass from 2 me near room temperature to 15 me at 5 K, plus the magnetic evidence for partial screening of the Mn magnetic moments suggest that these compounds represent rare examples of an underscreened Kondo lattice with Tₖ = 350 K.
