Reading our FamilyTreeDNA migration maps
How estimated paternal migration routes and ancient DNA discoveries fit into family research.
FamilyTreeDNA’s migration maps place our paternal haplogroup within a much older story of human movement. They also show archaeological individuals whose tested DNA connects with branches of that paternal tree.
What the route represents
FamilyTreeDNA describes the map as an estimated migration route to the ancestral haplogroup. The supplied map includes R-M222 and R-FT194071. Its arrows illustrate a proposed deep-ancestry route; they are not a sequence of documented journeys by named McManus ancestors. Source: FamilyTreeDNA migration map.
The useful questions are which branch is being shown, what evidence supports its placement, and whether a date refers to a shared ancestor or an archaeological sample. A route across a modern country does not establish a particular ancestor’s nationality or residence.
An example from Ballyhanna
FamilyTreeDNA identifies a paternal connection with Ballyhanna 331, whose remains were recovered in County Donegal and dated to 1031–1260 CE. Its analysis places the shared paternal ancestor on R-A259, estimated around 300 CE. The man buried at Ballyhanna and that earlier shared ancestor are therefore different individuals. The report cites sample Sk331 from Jackson and colleagues’ 2023 research. Source: FamilyTreeDNA ancient connections.
The supplied maps also list Kilteasheen and Derrynamanagh samples. Their individual reports need to be consulted before assigning detailed dates or relationships. An excavation location tells us where remains were found; it does not alone establish where our later McManus family lived.
Connecting ancient and recent history
Use the maps as context alongside our FT194071 explanation. For recent movements, follow land, work and migration in Ireland and the records of named people. Ancient material belongs with the Before 1700 timeline; related findings can be explored through connections.
