I find the ancestry ethnicity very useful
Especially where 1 great grandparent has totally different ethnicity
The common matches are accurate
At the moment I'm making a cluster of all DNA matches which have Swedish ancestry for someone and am seeing that I can zone in on particular lines .
my mother had 1 Scottish great grandparent & her matches with mainly Scottish ancestry connect to that line .
Even if they have no tree or closed trees I can add them to "Scottish" group and look at shared matches which do have trees .
Ethnicity reporting is most definitely still a developing process by Ancestry et al and hence caution needs to be applied to what is presented by the various websites.
As it is My Heritage has me way off the mark as to my own Ethnicity.
As it is mine is on Ancestry not showing as large a %age from a certain country as the family tree shows and each branch of said tree is now DNA validated at up to and beyond GG GP level. So whilst it is broadly right its deviation is off the mark.
It is easy to get hung up on Ethnicity but it does and can provide useful pointers.
Ethnicity reports will change over time as the database increases and the techniques used evolve.
Ancestry’s Pro Tools is a neat feature to help in Grouping DNA matches but there testing processes still can throw up surprises.
