King James IV is my 14th great grandfather, so going back, James III and so on should be 15th and 16th greatgrandfathers, but geni names them as cousins of uncles. The difficulty with my lines is that my mother and father are (unknowingly) 15th cousins and cousins in various other ways. Their lines intersect on many paths, so my ancestors are related to me in many ways. I wonder if the geni computer programming gets confused when there are multiple paths of relationships between two individuals?
