During the Lamperts ownership of the house the Queen Anne detailing was added to the wing section of the house, probably before Phillip Lampert's 1899 death. Lampert was born in Forreston but had moved to Belvidere by 1866. In 1875 Lampert began to teach school in and by 1883 he had been admitted to the Illinois bar. In 1889, after working in a law office in Chicago for a year, Lampert returned to Belvidere to open his own law and abstract office. On April 15, 1891 he married Clara Pape in Madison, Wisconsin. The couple purchased the Lampert-Wildflower House about five months later. Clara Lampert (née Pape) was born and educated in Forreston and graduated high school in 1887, for a short time after that she taught school in Ogle County, Illinois. She began working in Lampert's abstract office in Belvidere a short time after teaching, the law office opened in 1889. After Phillip Lampert died on December 5, 1899 Clara and her daughter Muriel (born March 28, 1892) were left poor. Clara continued her husband's abstract business and on February 2, 1900 she was appointed Deputy Clerk of Boone County, Muriel joined her in that office in 1912.
