Hello Rvarima.
If your grandfather was Olli Penttila buried on Dec 19th 1995 at Park Lawn Cemetery in Sudbury Ontario. He was my step-great grand father. I met him twice when I was a young boy before he passed away. He was a very kind man who had a very heavy finnish accent, and he always called me "Alik". He remarried in Ontario. The woman he remarried to was my great grandmother. Im not sure of her maiden name (I'm currently researching this). Her name was Sally, or Salli. From Copper cliff in Sudbury, Ontario.
Olli raised my father, aunt, and uncial as a step Grandfather. My father also told me to look into the names Jerry Penttila and Leo Penttila as those were my Grandfather's step brothers.
I am also looking into Park Lawn Cemitary in Sudbury Ontario, and came across an Anni Penttila who is buried there on Nov 15, 1979 at the age of 74. I have contacted an email address listed on the website requesting her obituary to attempt to discover some more information, and perhaps confirm a relation to Olli.
The website link is here for you to see:
