Hannah Parr deaths

My g. g. grandparents, their three daughters, and the wife's father, my ggg grandfather, were on the Hannah Parr. They are listed on under #75, Ellev Erlandsen Torgersrud, Ronoug Hansdatter, Matia Ellefsdatter (my g grandmother) Christine Ellefsdatter, Hanna Ellefsdatter. and Hans Olsen Torgersrud (Ronoug's father). The two younger daughters died on the journey. Are there any death records that can be obtained for passengers who died at sea, or in port while they were in Limerick? My Grandmother, who was the daughter of Matia, told me that when the baby died she was buried at sea, and other passengers had to hold onto the mother, to keep her from jumping in the ocean after the baby. Matia named my grandmother Hannah after the ship.
