DNA tests are perceived as more scientific conclusive and expeditious than searching the civil records. However, they are limited by restrictions on lines which may be studied. Also the civil records are always only as accurate as the individuals who provided or wrote the information
The aforementioned Y DNA testing results are normally stated as probabilities For example:- a perfect 12/12 marker test match gives a 90% likelihood of the most recent common ancestor (MRCA) being within 23 generations back, while a 67 of 67 marker match gives the same 90% likelihood of the MRCA being within 4 generations back
