Holzthum
Holzthum is a surname of German origin. It is relatively uncommon. The name is likely derived from a place name involving the elements "Holz" (wood, forest) and "Thum" (an old term for a village or an estate). Therefore, it likely originated as a descriptor for someone living near a wooded area or in a village near a forest. Further research into historical records and German genealogical resources may be necessary to ascertain specific origins and lineage.
