What¡¯s tough about evolving science of phylogenealogy is that we are learning more every month and year. ? ?Surnames are indicative not always definitive due to cultural and various wild card factors needed to predict at high confidence TMRCA ranges for SNP sub clades. ??
Historical and archaeological evidence helps us filter out fog and noise like polarized lenses helps reduce glare. ? Take the surname Lynch (and variations). ? ?Most importantly Lynch stems from ¡°mariner¡± or ¡°seaman.¡±
Think fleets of large ships engaged in trade, pirateering, battling across the Irish Sea and along coastlines and harbors in late Bronze and Iron Age, pre-Christian Ireland, Britain, Brittany and Scotland. ? ?Lynch clan descendants reflect multiple branches, similar to O¡¯Sullivan clan septs.
Lynch mariners were aligned with O¡¯Sullivan Bere, probably resulting in a few distant Lynch surname matches. ? Also, I have a distant Lindsey match at A1133, which falls under L270/FT43021 (my son¡¯s BigY terminal SNP).
For Welsh dna perspective, I look at surnames like Lynch because the mariner root ties to the Llyn peninsula, where we see Hill forts and standing stones comparable to western Ireland on Dingle, Iveragh, and Beara peninsulas. ? In pre-Eoganacht, pre-Christian centuries, what DNA seed was spread 30+ generations back??
My point: ? Y DNA helps us see surname clusters that are clear and logical, and others that drive relevant research and analysis to fill in narratives. ? ?For my Sullivan roots, McGillicuddy, Sugrue, Harrington, Lowney, Daly and Driscoll help focus my genealogical research in Kerry and Cork to crack our family¡¯s brick walls.
With more test kit results¡ªY and Autosomal¡ª I¡¯m learning more to help create our narrative and hopefully find our original 1847-49 pre-Famine civil parish.
