In 1991, Omer McGee helped compile a book on the descendants of Amos Kilburn and Henry McGee. This book is no longer in print. It does include the court documents when the McGee clan tried to gain membership in the Cherokee nation.
Omer's Find-a-Grave entry discusses his experiences during World War II. His wife's [Elinor Cole McGee] obituary has more details about their life together including pioneering the McGee Christmas Tree farm. She has her individual accomplishments, including graduating from UC Berkley at age 17, at that time [1930], the youngest person ever to receive a degree from Cal Berkeley.
