I think I’d feel the same, OP.
I’m very interested in finding out geographical origins, particularly since I have a dd with colouring that is certainly different from anyone on either side - more Mediterranean than anything else - so I’m convinced that we have a washed-up Armada sailor or two somewhere down the line! Particularly since 2 sets of GG-parents came from coastal Devon or Suffolk, so it’s likely that their ancestors had always lived in those areas.
So I’m going to have my DNA ‘done’ soon, but I wouldn’t want to be put in touch with hordes of distant cousins - TBH I have not so distant relatives I’m not keen on having much to do with anyway!
