Corney Keller has added photographs of the Ship accounts (scheepsoldijboek) for Isaack Dalgue, who arrived at the Cape on the ship Nesserak in November 1713, to the growing collection of these documents that he maintains on the eGGSA web site: Accounts from VOC Ships' Pay Ledgers 1662-1805.
These volumes contain details of all the men and all the transactions made on a single outward bound voyage. Each time a ship departed for the east, a new ledger was compiled in duplicate. When the ship reached Batavia, in Indonesia, one copy (schaduw-kopie) was deposited there and the other copy (meester-kopie) was returned to the Netherlands. It was the copies that reached home that survived and are now in the Nationaal Archief at the Hague.
The 18th century document of Death Notifications in the Cape Archives, on the page where Dalgue's death is recorded, has a note added by Colin Graham Botha: Vide wills of the Orphan Chamber vol 11 no 29 of 1795, Will of Isak Dalque (died 6.4.1759) and Sara van Wijk wherein he states his proper name was Johannes Augustus Dreyer.
