There are many people out here who would love to try and help you, but you will need to give much more information before anybody can start.
Which country? Which county/state? Approximately how old? Where and when were you born? Were you a first child - this can help to give some idea of parents ages. Do you know if your father had a trade? Even if you don't know the exact answers to these questions, any information you do have can give clues.
