         29 . The system of  claim 21 , wherein the first user and the matching user are related but previously unknown to be related. 
     
     
         30 . The system of  claim 21 , wherein the ancestral information pertaining to the ancestral origin of the at least one chromosomal segment of the first user comprises a table of countries associated with the first user's ancestral origin. 
     
     
         31 . The system of  claim 21 , wherein the ancestral information pertaining to the ancestral origin of the at least one chromosomal segment of the first user comprises a pie chart of countries associated with the first user's ancestral origin. 
     
     
         32 . The system of  claim 21 , wherein the ancestral information pertaining to the ancestral origin of the at least one chromosomal segment of the first user comprises a map of countries associated with the first user's ancestral origin. 
     
     
         33 . The system of  claim 21 , wherein the one or more processors is further configured to:
 receive an indication that a third user has a known degree of relationship to the first user; and   determine, based at least in part on the ancestral origin of the at least one chromosomal segment of the first user, a characteristic of the third user.   
     
     
         34 . A method of operating an ancestry finder database with hundreds of thousands of genetic markers to display an ancestry origin of at least one chromosomal segment of a first user, comprising:
 (a) determining, using one or more processors of an ancestry finder system, an ancestral origin of at least one chromosomal segment of the first user to be a country, a geographical region, or an ethnicity associated with a matching user, wherein:
 the first user and the matching user share the least one chromosomal segment, 
 the at least one chromosomal segment comprises at least one identical-by-descent (IBD) segment between the first user and the matching user, and 
 the at least one IBD segment has a length meeting a minimum length;
