R-U198 LYNN PHYLOGENY |

While all known R-U198 Lynns have retained R-U198 values for a number of key markers [DYS] which identify them specifically as R-U198: DF89 excl. type G, they also carry variations in nine other markers which set them apart as a distinct family within that haplogroup. These nine marker values are common to eleven known R-U198 Lynns who have been Y-111 tested. Those values are believed, therefore, to be the ancestral values for those markers in the R-U198 Lynn family and to have occurred in a generation predating, by some centuries, the earliest known ancestor of any R-U198 Lynn who has tested (the "original R-U198 Lynn").
In addition, the mutations illustrated below occurred in one generation or another after the original R-U198 Lynn and thus resulted in new lines or branches within the family of R-U198 Lynns. These changes include two instances in which it is believed that a "back mutation" has occurred; i.e., a marker the value of which first had changed from the R-U198 value and later mutated back to the R-U198 value. While these mutations indicate which R-U198 Lynns are more closely related to one another, none of the mutations are evidence of the relative distance between living descendants of the various lines and their common R-U198 ancestor.
In the following illustration, colors correspond to those on the charts of Y-DNA results (Y1-67 and Y68-111), except for slight color differences here among the three men in the new line YCAiib / DYS549 - Mark, Milton, and Jeffrey. Those color differences reflect relatively recent changes. Note that Robert H. and Brian do not presently appear in the Y-DNA results charts because they tested with a different lab from everyone else.
All R-U198 members of the Lynn project at FamilyTreeDNA have been tested at Y-111. A smaller number of values may be common to Lynns outside the project (e.g., Robert H. and Brian), who might have tested at Y-111 or at just Y-67 or Y-37. The mutations illustrated above are shared as follows :
The paper trail indicates that Milton is more closely related to M. Woodward and Jeffrey J. than he is to M. Ch., although Milton and M. Ch. both have the R‑U198 value for marker YCAiib and M. Woodward and Jeffrey J. do not. The probable scenario is this: the mutation from 22 to 21 at YCAiib occurred in a common ancestor of M. Woodward, Milton, and Jeffrey J. (i.e., an ancestor not shared with M. Ch.) in just the last 7-8 generations; and then, Milton's line more recently experienced a back mutation to 22 at YCAiib.
