For first, this is loose group of szlachta colonists, with assistance of Jewish crafters, local serfs and in smaller case, religious minorities. The colonists emerge from Pommeranian voivodoship of Polish-Lithuanian Commonwealth, and are primarily Catholic and Lutheran Christians (with Jewish crafters being followers of Judaism and religious minorities following Calvinism). Being interested in colonial adventures Prince of Curland took, the head of local nobility, Hieronim Chrzanowski (I couldn't find historical person from the area, so I decided to invent the name) applied with association of other Pommeranian nobles to get a charter from the Sejm and the King to set up colonial expedition to the new world, composed of szlachta themselves, chosen group of their serfs and a group of townsfolk to set up functioning colony, responsible before Sejm and King himself. The charter was granted, and the group purchased a small armada of ships capable to transport about 200 people into colony, with provisions such as food, alcohol, clothing, muskets and sabres with ammunition for defence and seeds and small herd of animals for setting up functional agriculture in the colony. The colonists promised to pay taxes for the crown, planning to set up trade with Poland-Lithuania as source of their income.
The size of the group was 200 people in total and about 100 animals (cows and sheeps).
