Rev. Edmund Leigh, chr 1736, d 1819

Two descendants of the Rev. Edmund Leigh had their Y-DNA tested for 67 markers. These descendants are of the I1 haplogroup.

A descendant of Samuel Leigh has the ysearch ID of 66XXS. As explained in the welshleigh site, his DNA markers are a perfect match with those believed to belong to Ralph Leigh, and this descendant is the reference for the genetic distances given in this page. The genetic distances reported in this website will be given relative to Ralph Leigh rather than to this descendant. This descendant also had his Y-DNA tested by Ancestry for 47 markers. Because the Rev. Edmund Leigh is in the line having the perfect match with Ralph Leigh, unless compensating mutations occurred, the Rev. Edmund Leigh also has a perfect match with Ralph Leigh.

A descendant of Rector Daniel Leigh has the ysearch ID of H8G3U, and his genetic distance from Ralph Leigh and from the Rev. Edmund Leigh is 4. The difference between this descendant and the Rev. Edmund Leigh is only five generations, and the genetic distance would normally be less than 4. However, the genetic mutation that caused the genetic distance of 4 happened to be in markers that change rapidly, causing the genetic distance to be larger than normal.
