I've indexed over 75 entries of the name Eichholz or Eichholtz in my collection: "Milwaukee's German Newspapers; an index of death notices and related items". The project started in 2007 and covers daily and weekly papers from 1844-1950.
For instance, there were multiple family death notices and Danksagung published for a William Eichholz (May 1917) in the morning and evening editions. And there were the same family notices and an obit. (of some sort) for Augusta Eichholz in 1911.
