Anna Rosberg (also known as Annie Rosberg or Anna Rosenberg) is the daughter of "S.B." Rosberg (also known as Sven Bengtsson Rosenberg) and Karna Pehrsdotter (also known as Karin Person). She appears to be the first child of her family born in the United States after her parents' arrival from their native Sweden in 1865. The couple originally hailed from Skåne County (formerly known as Kristianstads County) and were married there in Nosaby in 1862.

Anna was the second Anna born to her parents. The first Anna, her older sister, was born in Sweden in 1862, but died just a few months later. She also had an older brother Nils, who was born in Sweden and died in Chicago in October of 1866, a year before she was born. Her mother gave birth to another child in Chicago that we know of, a stillborn baby born in June of 1871, when Anna was 3 years old.

Due to the deaths of her siblings, Anna's childhood experience was probably similar in many ways to being an "only child". However, census records, church membership records, and city directory listings reveal that she also had a large extended family around her in Chicago and many young cousins whom she likely knew well and played with often.

Her parents were known to own two properties in Chicago during the late 1860s and early 1870s: 93 Superior Street, and 111 Hickory Avenue on Goose Island. Anna's paternal grandparents Bengt and Nilla (also known as Nellie) Person were also resident at those addresses, and at various times so too were Anna's paternal aunt Anna Nelson and her family, Anna's maternal aunt Kersti Swenson and her family, and maternal uncle Nils Pearson with his family as well.

Anna's home likely served as a nexus of Nelsons, Swensons, and Persons not only because of their close family ties but also due to the fact that many of them were also involved with her father's tailoring business, which sometimes operated from the same properties where Anna and her parents lived.

Just after Anna's 4th birthday, from 8 - 10 October 1871, she and her family experienced one of the most destructive and iconic touchstones of Chicago history: the Great Chicago Fire. The Rosberg family was personally and heavily impacted by the blaze, suffering not only damage to their home on 93 Superior Street, but the tragic loss of Anna's paternal grandfather, Bengt Person, who died during the fire.

Anna's brief life came to an end a year after the fire, on the 7th of October 1872, at the age of 5. It was a difficult season of loss for the Rosbergs and their extended family. In August of 1872, Anna's little 16-month-old cousin Ellen Christine Nelson had died. Just a couple of months after Anna's death, her 2-year-old cousin Charles Swenson also died. These small cousins and playmates were all buried in the same section of Wunders Cemetery, then known as "German Lutheran Cemetery".

Her burial record in the books of Saint Ansgarius Episcopal Church reads as follows:

"1872, (buried) October 8; (died) October 7; Annie daughter of Sw(en) Rosberg; (aged) 5 years ".

Her Wunder's Cemetery burial record is under the name Anni Rosberg, and notes that she was buried October of 1872 in Block B KIK, Grave #4340.
