I'm looking for any information about William Frederick Mueller, my great-grandfather, who was born in Quincy, IL on Sept 30, 1878 or 1879; as well as information on his family. His parents were Reinhold Mueller and Luise Behr. Luise had siblings in Quincy or Bloomington, but I don't know much about Reinhold. She died in 1881. He had an older brother, Herman, who died when he was 18. He had four children: Gustav, Louisa (my grandmother), Henry, and Lincoln. Would appreciate any leads. Thanks. Jose Reyes
