Christopher Olsen of Oslo..looking for any info

I live in BC Canada, I am a decendant of Christopher Olsen of Oslo, Norway. He would've been my great grandfather, he came to Canada in the early 1900's. I don't know much more, just that I definitely have a number of relatives in Oslo that I would love to have contact with. a little more information, Christopher is my granfather Ernest Olsen's father along with his brothers Herman Olsen and Howard Olsen, if you have any information on any other relatives and more information of this Olsen family please get back to me on this information.......I would hope to some day meet more family (decendants) of Christopher Olsen Thank you very much!!
