Magdalena Garramone Guerrieri (1860–1926 ) and Giovanni "John" Guerrieri (1853–1927) had married in 1884 and emigrated from the Brindisi area in southern Italy to America in 1891. Magdalena gave birth to nine children but by 1910 only five survived.  In 1903 the family lived at 135 North Sangamon in Chicago, about four blocks from the Iroquois Theater.

In the Guerrieri Iroquois Theater party:

• Anna B. Millikin  (or Milliken) survivor of unknown relationship to the Guerrieri family, burned on face and hands
• Eleven-year-old Vingenzia "Jennie "Guerrieri (b. 1892), fatality
• Seventeen-year-old Raphael Felix "Ralph" Guerrieri (1886–1956), injured survivor
• Ten-year-old Anthony "Tony" Guerrieri (1893–1960), survivor
• Seven-year-old Celestina "Jessie" Guerrieri (1896–1972), injured survivor

Jessie and Raphael were both seriously injured at the Iroquois and taken to St. Lukes hospital. 

Jennie Guerrieri had attended the Moses Montefiore school. Reportedly found suffocated beneath a pile of other bodies, her body was identified by her older brother, Michael Guerrieri.  She was buried in Chicago's Calvary Cemetery.

Ralph Guerrieri's ears and hands were badly burned while trying to save his siblings, his hands remaining crippled enough that it was cited as a disability on his WWI draft registration over a decade after the fire. He was nevertheless able to work as a commercial artist and did so from at least 1910 to 1930. In 1917 he worked for the Ernest J. Kreutgen Engraving company at 626 Federal Street.  (Kreutgen would go on to become the Chicago postmaster.)

According to his WWI draft registration, Ralph had black hair, blue eyes and was stout. In his early forties he married a woman named Mary.  A descendent reports that he wore his hair long throughout his life so as to cover the burns on his ears.

As an adult, Tony Guerrieri worked off and on in the garment industry, sometimes as a tailor, other times as a cutter.  He also tried his hand at sales, working for a confectionary company.  He married Jessamine Isso and had two daughters.

Jessie Guerrieri married Nicholas Colucci and they had two sons, Victor and John.

Anna B. Millikin (or Milliken) lived at the Thompson's European Hotel at 151 Dearborn street.  That's all that was reported about the woman. The hotel was owned by John R. Thompson of Thompson's diners.  Newspapers and the Marshall disaster book published an inaccurate description of the Guerrieri party experience, identified as a quotation from Millikin (below), that she was likely dismayed to read.

There were several women living in Chicago that might have been Anna, last name Millikin, Milliken, Milligan, Milligen and Mullikan, but I've failed to tie any of them to the Guerrieri family.

The prominent and wealthy widow of James Millikin, founder of James Millikin University in Decatur, IL, was named Anna B. Millikin.  She founded and financed a home for widows and orphans in Decatur, the Anna B. Millikin Home.  She did spend time in Chicago and was a patron of the arts, but it seems impossible that newspapers in Decatur and Chicago would have overlooked the opportunity to make much of her prestige and improbable that they didn't learn who she was.  Then too there is the reference in the newspaper clipping below to her having survived the 1871 Chicago fire.  A Decatur woman in Chicago at the time of two great fires?

It is likely the story above, that appeared in the newspaper and in the Marshall disaster book, came from an inaccurate story by a third party.  Since Jennie was deceased, Anna cannot possibly have gathered after the fire with all four children.
