"European genealogical practices vary by country and culture, but generally involve researching and documenting one's ancestry and family history through records such as birth, marriage, and death certificates, church records, and census records. Many people in Europe also rely on oral tradition and family stories passed down through generations to learn about their ancestors. Professional genealogists may also be consulted to help with research and to verify and organize the collected information. In some countries, such as Ireland, there are also specific genealogical societies and resources available to aid in research."
