The 1900 census shows Caroline as having five children, with five living. Josephine is in the Orleans Parish birth index, born 1883, but I've found her nowhere else. It's possible she died young. It's also possible that Adina's first or middle name was Josephine.
Caroline's last name could be spelled Rednaur or Redner. Other spellings I have found are Redenhauer, Rednauer, and Redman.
Caroline's birthplace is listed as Germany in the 1880 census and Louisiana in the 1900 census. Her month and year of birth were taken from the 1900 census.
None at this time.
