Looking to encourage participation from direct male descendants of Hastings known to be from south of Westport in County Mayo. I'll have two participants to start from and see what family groupings we can put together to determine kinship. The first one is back and shows a possible descendancy from Nial of the Nine Hostages, which means very early Irish history.
