For me:
Ireland (Counties Cork, Kerry, Limerick and Mayo)
Scotland (Edinburgh, Glasgow)
England (Nottingham, London, Kent, Surrey, Sussex, Cornwall and Devon, Dorset, Merseyside and Liverpool and Gloucester)
France (Brittany, Occitanie, Aquitaine, Paris and Provence)
Germany (Rhineland)
The Netherlands (Amsterdam and Utrecht)
Sweden
Denmark
Norway
Faroe Islands
Iceland
Portugal (Lisbon)
Belgium
Switzerland
Czech Republic (Prague)
Hungary (Budapest and surrounding villages)
I'm a little all over Europe (and some research is extended into North America and Australia, as some distant great aunts and uncles migrated there after the Irish Famine). Most of my research is focused in Ireland, Scotland and England though.
