1. A Smith whose family interchangeably uses the surname Mac Gabhainn showed up as a new member to McGowan Surname Project.
2. His DYS19 is 14-17.? My first time seeing
3. His DYS459 is 9-9 which matches to all other Cavan Smith of which I am aware.
4. If I employ administrative tool “Genetic Distance” to establish matches within project, 7 of 16 Cavan Smith show as Genetic Distance = 3.

?

I am guessing that this person’s DYS19 14-17 reflects a duplication plus divergence ?
Butler et al., 2005 Forensic Sci.50:4 Chromosome Duplications Along the Y-Chromosome and Their Potential impact.

?

Butler’s paper documents at least 7 occurrences of duplications at DYS19 (DYS394)

?

Am I above the target or off target ?
