NobleCircles Genealogy © Sadolin is a searchable genealogical relationship database consisting of more than 450,000 individuals – all within the framework of one single family tree – mapping our ancestors and their various relatives.

The database has only one major "rule": Each person stated is in some way related to anyone else stated. This would be through blood, adoption, or marriage relations. We continue trying to get all facts in the database verified by the families and/or genealogists, archives and records, publications – such as books, almanacs, calendars, etc. However, with such a huge database, missing information, mistakes, etc., occurs, and if you see them or if you have updated information, please feel free to forward us your comments and proposes.

The database combines royalty and nobility (peers) with non-peers such as knights, gentry, yeomen, husbandmen, tradesmen, cottagers, and patrician lineages from mainly Scandinavia/Nordic countries (Denmark, Norway, Sweden, Finland, and Iceland), Germany, France, Ireland, and United Kingdom – and their descendants in North America, Latin America, Africa, and Oceania.

While the noble families generally were manor and estate owners (farmers), the patrician lineages were generally artists, civil servants, educators, military officers, politicians, priests, and scientists. The database also includes many of the "newer" finance, industry, and trade lineages – since also these married into the nobility, gentry, and patrician lineages – as well as into each other.
