I've previously posted Lillie MILLER's obituary, which states that among others, she was survived by a brother, John SCHAEFER.
The Browning Genealogy Obituary database contains the following obituary card for a Peter SCHAEFER.
So, now we have possibly two brothers for "Lillie"; Peter and John. Even though Peter's obit card refers to her as Lillian, and spells Schaeffer with only one "F", I still believe we have the same family. In the 1900 census of Vanderburgh County, Indiana, Lillie is listed as Elizabeth MILLER, age 27, white female, born March 1873 born in Indiana. In the 1910 and 1920 census, she is listed as Lizzie MILLER. Her obit card in the Browning Genealogy Obituary database lists here as Mrs. Lillie MILLER:
Looking for Lillie in the 1880 census, we find the family of Charles and Mary (RIEBER) SCHAEFFER in Evansville, Vanderburgh County, Indiana.
Charley SCHAEFFER, a 27 year old varnisher, was living at 812 Second Avenue in Evansville, Vanderburgh County, Indiana. He was born in Louisiana and both parents were from Germany. His wife, Mary, was also 27, born in Indiana with both parents born in Germany. Children were listed as : Lilly, aged 7; Peter, aged 5; John, aged 3; and Katie, aged 9 months; all born in Indiana.
According to Ray Bland, he's found evidence that Charles shot and killed his wife, Mary, on September 16, 1883. There is a memorial for Maria Eva (RIEBER) SCHAEFFER on the Find A Grave website, buried in St. Joseph Catholic Cemetery in Evansville. Maria was the daughter of Peter and Elizabeth (SCHUHMACHER) RIEBER.
More research needs to be done, and it looks like I have a few new leads to check out.
