Thank you Ben!
I don’t have any information about their kids, I suspect there were none,
in this case I’ll be looking for the death records and perhaps graves?
I looked at the name lists of the Regeringsalmanak voor Nederlandsch Indie
under you link to the Berlin library, but couldn’t find any Makowiecki (or misspelled Mackowiecki)
in the name lists at the end of the books.
Have you used some other source for this information?
“1909 Makowiczki, W. plant chief Petrol Mij Perlak te Ida (married with P.A. Walther)”
Kind regards,
Wojciech
