Catrina Bouman
(Witness) Will On 24 January 1727, Jonker van Macassar 'appeared' before the Secretaris or Secretary of the Council of Policy, Daniel Thiebault, to execute his will with the assistance of a Portuguese interpreter. This assistance may have been accorded to him due to his royal status. He was in fact ill and confined to bed, so the official would have come to him. However, there is nothing in the record which indicates the will was ever probated. There are several edits in the original will. He is described as a Vrij gegeevene Leijffeijgen known to the Secretaris. His de facto wife Rosetta van Java named on this occasion as Rosetta van Java, is first described as sijne Concubine, this is deleted and substuted with de vrijswartinne. To her he bequeaths the slave Alexander van Couchin and stipulates that this bequest cannot be contested. To their son and daughter Jacob Jansen and Johanna Jonker, he leaves the slave September van Manda. A comment describing Jacob as door een ander persoon geprocreeert was crossed out, but at his 1730 baptism Jacob is described as halfslag, indicating his father was white and that he was therefor not the biological son of the prince. To his other son and daughter Jacob Jansen and Johanna Jonker, he bequeaths the slaves Cassamie of Origin Unknown and Fortuijn van Bougis. All of the slaves were to remain with his de facto wife until the children attained their majority. Rosetta van Java also inherited the residue of his estate except for Rds 50 given to Jacob to assist in raising the other children to majority.
