Sisters Connie Manz, of Pasadena, California, and Catherine Manz Smith, of Veneta, Oregon, knew their grandfather had once lived in Spokane. They knew he’d married their grandmother here in 1909. But they didn’t know, until January at least, that their grandfather was an architect who’s credited with designing more than a dozen homes in Spokane. Many of the homes are still standing on the South Hill, near Manito and Cannon Hill parks.
