Archeological efforts are underway to pinpoint Bill Monroe's exact birthplace in Rosine, Ky. The Bill Monroe Foundation, a group of 16 investors who are developing a state park honoring the late "Father of Bluegrass Music" in his hometown, spearheads the project. An archeologist has begun a dig to date the stone chimney in a house now standing on the farm where the Country Music Hall of Fame member was born in 1911. "We have reason to believe the interior chimney is 70 to 80 years older than the house," Campbell Mercer, the foundation's executive director, says. "This would indicate that the house was built around the chimney which belonged first to the cabin in which Bill was born. It is generally thought that the cabin burned down when Bill was five years old. People have always wondered where the cabin was located. We think we'll be able to tell them." The foundation recently bought Monroe's 1923 Gibson F-5 mandolin for $1.125 million.
