I recently did a DNA test and found out that I am 57% British and 19% Irish, Scottish and Wales, 17% Scandinavian, 3% European Jewish,... I live in the US. My maiden name is "Coffey." I have PA (autoimmune) which began at age 58. Since the PA society is in great Britain, I am wondering if PA is a more common disease of the British? I seem to had read that it was more common in Northern Europeans somewhere? Any insight?
