Amateur historians Kathleen and Douglas Jones carefully leafed through the stack of handwritten World War I soldier records looking for clues.
They were digging for details, including soldiers' occupations before the war, where they served and names of kin that — when pieced together — will tell the stories of the more than 900 men and women who left Dakota County to serve.
"It's really detective work," said Kathleen Jones, describing the effort's appeal.
The Apple Valley couple is part of a new team of volunteers compiling a database of all county residents who served in WWI for the Dakota County Historical Society.
Many folks have heard of citizen scientists — volunteers who monitor weather, birds and bugs and report their observations to experts who use the data to make discoveries. The south metro Historical Society has borrowed that concept and launched its first citizen historian project, called "Adopt a WWI Soldier."
The response has been overwhelming.
"We were hoping for about 15 to 20 [volunteers]," said Matthew Carter, Dakota County Historical Society executive director. "Right now we are working with about 80 volunteers."
Volunteers range in age from college students to retirees, but all share a love of history and a knack for sleuthing.
