Sorry, no etymologies found.
However, the evidence clearly shows west to east to be more likely; the fossil trichechine phylogenetically closest to Trichechus (Mio-Pliocene Ribodon) is South American, and in fact all fossil trichechines are American; T. manatus and T. senegalensis are more like each other than either is to T. inunguis; the nematode parasites of T. senegalensis seem to more specialised than the nematodes of T. manatus, and so on.
