Son of Arthur Hull's deceased brother Fred J Hull; recently adopted by Arthur.

Albert K. Polzin Jr (1870–1949) and Bertha Polzin Koehler were two of seven children born to German immigrants, Albert Polzin Sr (1845 – 1925) and Henrietta Rieck Polzin (1843–1931). Albert Jr was born in Germany and immigrated to America in 1862 with his parents and Bertha was born in Illinois after the family's emigration.

In 1883 Albert Jr married Illinois native Elizabeth Dehnhardt, and they had three children, of which two were still living in 1900: George Albert Polzin (1883–c1950) and Henrietta, who perished at the Iroquois. Albert worked as a grocery clerk, and they owned their home at 41 Ashland in La Grange, Illinois, a village southwest of Chicago with a 1903 population of around 4,000. Today La Grange is considered a Chicago suburb. Albert and Elizabeth's home was probably located where the playground is today at the Cossitt Elementary School.

The photo portrait pictured the Martin boys six years before the 1903 Iroquois Theater fire where they lost their lives during a Mr. Bluebeard Christmas pageant. It was perhaps the only photo the family had or was willing to part with. The Chicago Daily Tribune ran the picture with a caption saying the boys were six and eight years old instead of their actual twelve and fourteen. Robert Bass Martin and Harold Campbell Martin went to the theater with their parents, Dr. Daniel R. Martin and Clara B. Campbell Martin.  Daniel Martin found and identified the bodies of both his sons at Rolston's Funeral home.

The Martin boys' funeral was held on January 2, 1904, at the St. Joseph's chapel at 121st and Eggleston in Pullman.

On February 13, 1904, Daniel and Clara testified about their Iroquois Theater experience before the special grand jury.

On December 30, 1903, Albert Polzin's wife and daughter, Elizabeth Polzin and Etta Polzin joined his sister and her daughter, Bertha Polzin Koehler and Marie Koehler, for a matinee performance of Klaw and Erlanger's Mr. Bluebeard production at Chicago's newest playhouse, the Iroquois Theater. When a stage fire spread to the auditorium, nearly six hundred perished. Elizabeth Polzin and Bertha Koehler escaped; Etta and Marie were among the fatalities.

Marie's body was located at Buffum's funeral home and Etta's at Perrigo's funeral home. Reportedly the only evidence of injury to Etta were reddened spots on each nostril, interpreted by family as having resulted from breathing in fire. Nothing was reported about the condition of Marie's body but reports of Bertha searching morgues for a day and a half suggest her daughter was sufficiently burned to make recognition difficult.

It was reported that Elizabeth Polzin was taken to Marshall Fields department store, and Bertha was later interviewed at the Great Northern Hotel. Though Bertha was said to have suffered severe burns to the head and face, and Elizabeth was reported to have been burned, neither woman was hospitalized, and injury did not prevent Bertha from spending many hours searching for her daughter.

Bertha married Fred Koehler (1852–1917) in 1887, and Marie was the only child. Fred immigrated to America from Germany in 1852 and from at least 1893 to 1904 was a saloon keeper. Despite reports to the contrary, in 1903, the Koehler's probably lived in Washington Heights, a Chicago suburb. See discrepancies below.

In the years after the fire Bertha Koehler, Albert, and Elizabeth Polzin all moved to Los Angeles in the 1920s and spent the remainder of their lives there, and were buried in the Forest Lawn Memorial Park in Glendale, CA.

In 1909, Marie Koehler's family received one of the thirty-five $750 settlements from Fuller Construction, the company that built the Iroquois Theater.
