Looking for info about the BOLDUAN-family in the former Dutch East Indies. Franz Hermann August came their as a gunner with the Royal Dutch Colonial Army(=KNIL) around 1882. He was born in 1859 in the town of Koeslin/Pommerania (nowadays Koeslin, Poland) and died in 1921 in Palembang/Sumatra. He married Louise SCHLINGER and the couple had 4 children. Any info about members of The BOLDUAN-family is welcome.
