Rykounoff Mikhail Sergueievitch

I am looking for relatives of my grand father Mikhail Sergueievitch Rykounoff born on November 8th, 1898 in Sibir from Serguei Rykounoff and Fioklin Pozanova. He left Russia during the Revolution with one of his brother, spent some time in England where he worked in coal mines then came to France in the 20's and settled around Paris. He met my Granny Anna Halata, who had come to France around 1922 with other Polish emigrants (she always claimed she was Ukrainian as she was born near Lvov). I know very little about their previous lives : my Grad Dad died in 1965 when I was 10 and my Granny burnt every paper which could help me short before her death in 1999. And she didn't want to talk about the past.
They had two daughters named Maria and Olga (my mother).
I know these first names were those of my Grand Dad's two sisters. My Grand Dad's family was very large : he had many brothers and only two sisters. I also know he heard from his brother (the one with whom he left Russia) before his death : this brother had finally come back to Russia in the late 50's or early 60's. My Granny could hardly read or write, so we could never stay in touch with this family.
Thanks for any information you could send to danielle.savina@tele2.fr. I can read and understand russian.
