My wife is Irish and Scandinavian, her maiden name was Stalcup (Steel Cap), I am Irish and English Great Grandma spoke Celtic and mom couldn't understand her for the longest time. Any way those of Irish decent have a small chance of carrying a gene for Hemochromatosis. This disease limits the absorption of Iron which then builds up in various organs and causes trouble. My wife has the gene and the disease, and both my boys have it. Treatment is giving blood at first very often every two weeks in my wife case initially. Diet is restricted all food low in Iron. It is almost asymptomatic until it has done much damage. They didn't catch my wife's in time and now she has nonalcoholic liver disease, We are in the process of trying to determine how bad. If you are of Northern European ancestry, might was to consider getting it checked next time you see the doc.
