looking for the truth

growing up I always new I had a sister and I always new there was a twin. What I do not know is if it is my twin or my sisters.I told people I new these things and my mother would always lie and say it wasnt so. Then one day I recieved a call from a woman claiming to be my sister. I had her checked out through contacts of mine and I went to toronto canada to see for my self. My god she was the spiting image of my mother and me. After checking it all out she was my sister. she was 30 at the time. I then phoned my mother and her family and the truth came out as her family didnt even know she gave birth. She says there were twins but wont say who is the twin my sister or me. I believe its her who has the twin but my mother refuses to say who it is or where the child is at. I believe she does know the answer. I introduced my sister to her other siblings and her birth mother and her real father who I also found. I was born oshawa general hospital december 18 1958. My sister was born toronto general hospital july 12 1964 our last name is giebel. My mother has now skipped the country and is living somwhere in scotland. However before leaving she made the statement to my sister to tell me that in the end when she dies I will know the truth about everything. I need the truth now I need to complete our lives and family now before to much more time is lost. I already missed out on the first 30 years of my sisters live.
