The town of Sibley has had a rich history which dates back to the early 1800's, making it a perfect place to start a chapter of the DAR.  The first settlers in Jackson County came up the Missouri River to Sibley, where Lewis and Clark had established Fort Osage.   Lorine H. Morrow was the organizing regent of Fort Osage Chapter DAR.  The chapter's first meeting was held at the Johnson House in Sibley in 1947.  The Elizabeth Benton Chapter was considered its "mother" chapter. 

Members Mrs. Hilt, Mrs. Henthorn, Mrs. Sams, and Mrs. Ravenscraft helped organize the Fort Osage Chapter.  Jennie Hilt and Lela Ravenscraft later became members.   Lorine Morrow's mother, Nolia Hostetter, and some of the Fort Osage Chapter DAR members sold post cards, slides, and stationery at the Fort to support their scholarship program.  One member, Rhoda Woldridge, sold her children's books at the Fort, and in more recent years, Doris Reed spent many hours working there.   Clara Lee compiled the history of the one-room schools in the area, which was later published by the Fort Osage Chapter as In the Beginning: How the Fort Osage Schools Began, Fort Osage Administration 1959-1969.  

The chapter also cooperated in establishing the Fort Osage Historical Society and assisted in the events sponsored by it for the benefit of the Fort.   Many talented and noteworthy ladies have been members of the Fort Osage Chapter DAR.  To name a few of the earlier members: Hazel Reppert, Doris Cooper, Mary Jane Truman, Ruth Lenox, Lucille Johnson, Grace Carmean, Birdie Davidson, Margaret and Mary Sue Chiles, Edna Scurlock, Winona Burgess, and Dora Slaughter.
