An invention for authenticating artifacts related to President Abraham Lincoln is presented. In an embodiment of the invention, an artifact is identified. The artifact has a biologically-derived component (“bio-component”). At least a portion of the bio-component is processed to yield matter that may be analyzed. This matter is analyzed and the analysis results interpreted. The interpretation is based on information related to a syndrome of marfanoid habitus and stable multiple lip dysmorphisms (an “MH/LD syndrome”). Two such syndromes are multiple endocrine neoplasia type 2B and pure mucosal neuroma syndrome. Other such syndromes may exist. Evidence of an MH/LD syndrome in the analysis results is evidence that the artifact is authentically associated with President Lincoln. A report is optionally produced.
