“The Pinc,” as the new owners now affectionately call it, has seen plenty of history through its jewel-toned stained glass windows at 202 M Street in Eureka. Located on Humboldt Bay, the majestic, historic home was built in 1889 by lumber magnate William Carson as a wedding gift for his son J. Milton Carson and his wife Mary Amelia (Bell) Carson. William lived across the street in the famous Carson mansion, considered one of the most magnificent Victorian homes in America. The J. Milton Carson House, known locally as “The Pink Lady” over the years, is crowned with iconic, ornamental Victorian features. Famous as a classic example of the Queen Anne architectural style, its large bay windows, delicate cornices, graceful spires, and lace gingerbread trim attract tourists and architecture lovers alike.
