1902 City Directory and Payroll. Leroy Heylman, son of Charles Heylman went to work there as a "toolboy" at the age of 15 in 1903. Charles is found in a April 27, 1902 Payroll for extra work when he was part of a select crew that spent that day, a Sunday, setting the statues. They both worked as engineers for their entire lives in St. Paul and raised families here. I believe their descendants still live in the area.
