I am trying to find out details of my paternal grandfather.  His name
was Boris Jascolt (or Jascolts) and it is believed he was born in
Russia in the early 1900's.  He moved to Riga, Latvia and in 1932 or
1933 he married Lydia Kuzina and they had a son, Igor, born in 1934. 
They divorced two years later.

I am trying to find out any information about him including where he
was born, in what year, if he remarried, has any other children, his
occupation, the year he died and where he is buried.

Well you should try this link, try to fill in all the information you
have and check it from time to time to see if sth appears, thanks and
good luck (dont forget to include the countries on the description )
