 "Hem" is the same word as Old English "hām" (home), the Old Low Franconian form would have been "*haim".Another explanation for the name etymology is the Old Low Franconian "*Liuthari-ing-haim" "home of Luithari's people".Ernest Nègre notices that the Germanic "-heim" (sic) is precisely rendered by the Latin "mansiones" in the earliest document.
