pronunciation of a Latvian(?) name

[Junichi Miyazawa]

Dear colleagues,

Sorry for a marginal post.

I happened meet a Latvian (maybe) name
in an English text I am translating into Japanese:

  V. Krastins

The text is a letter from a Canadian pianist written in 1963,
and the person is the addresse, who lived in Riga then.

Is it a Russian name or a Latvian name?
How shall I pronunce it?
I need to know the pronunciation
to transcribe the name into Japanese *phonetically*.
I am particularly know wheater the last letter "s" is voiced
or un-voiced, and where the accent is located.
Is  Latvian accent different from Russian?
(If it is a Russian name, I know how to pronounce it.)

Thank you in advance.   Please reply off-list.

Regards,

Junichi

P.S.  Mr. Krastins lived in "Zutenu 1-6" in Riga.
How to pronounce "Zutenu"?  Like a Russian word?
