Yes,that,s what it said.Here is what it says. If the people have the same last name as you there is a 90% chance that you are related within the last 15 generations.If the dna is similiar to another person and you don,t have the last name there is 50% chance that we are related.A generationis generally measured in 25 year segments.Since we do have the same last name,our relatives probably crossed paths within the last 15 generations,or 15x25 -375 years. I have found out one thing through all of this we are all related,everybody.It shows through we are all diffrent we are all the same.I,m so happy that you told me that one person in my family was all Temne from Sierra Leone i have a scrap book just with them in it.
