Last fall, some friends in Bob Coughlan’s ballroom dancing class mentioned they were taking a weekend trip to Philadelphia for a teacher’s conference. Coughlan, the great-grandson of T.R. Coughlan, who founded Mankato Kasota Stone in 1885, immediately offered his input on the couple’s itinerary while in the city of brotherly love.
“If you’re going to Philly, you have to go see the Philadelphia Museum of Art,” he told the couple. “My grandfather supplied the stone for that building.”
