Hello luceee,

Here's what I was able find out regarding obtaining birth or marriage
certificates in Indonesia.

"BIRTH CERTIFICATE
Available. A birth certificate (Akte Kelahiran) may be obtained from
the Civil Registry office (Dinas Kependudukan and Catatan Sipil) at
the place within whose jurisdiction the birth took place. This
certificate is available upon request throughout Indonesia."

"MARRIAGE CERTIFICATE
Available. A marriage certificate (Akte Perkawinan or Surat Nikah) is
issued by the following offices for the following population groups:
1) Moslem - the Kantor Urusan Agama (KUA - Office of Religious
Affairs); 2) all other religions - a solemnization certificate must
first be recorded with the Civil Registry office (Dinas Kependudukan
and Catatan Sipil). Please note that the marriage is considered
legally valid from the date of recording, not the date of
solemnization."

The above paragraphs are quotes taken from the following page:

Both the quotes refer to the Civil Registry. I believe I found the
phone number for one of these registries. It is +62 (21) 566 6242-44
(KANTOR CATATAN SIPIL). I found this number at the following link:

You are correct about the year of marriage to Catherine Boardman.
According to the link below, she was married to Hewetson on April 2,
1823. I'm assuming she married William as per the births further down
the page, they have list a son named Henry William. The link is:

I hope this provides you with the information to obtain the
certificates you are seeking.
