Stephen Ackerman said to have been born in Indiana about 1864, married Margaret "Maggie" DOYLE. They had three children: Thomas - born Nov 1889 Illinois, Margaret - born 22 Aug 1894 Chicago, Illinois, and Josie - born April 1896.
Found Stephen and Maggie's marriage info "Illinois, Cook County Marriages, 1871-1920," index and images, FamilySearch
Sometime between 1896 and 1900 Stephen disappears from records. Have no idea who Stephen's parents are.
Have no idea what happened to Thomas and Josie.
Margaret Ackerman, the daughter, married Charles H. Peters. All I know is that they had one known child: Sadie born 21 Apr 1913 in Chicago, Sadie died 6 May 1914 Chicago and is buried in Calvary Cemetery in Chicago.
Any help with any of this would be extremely appreciated.
