Welcome to the world of genealogy....find one piece of the puzzle and then hit a dozen brick walls. :) they do say that genealogy is for those who love doing puzzles.
Do try and get family members to record their memories of their childhood. Older family might be able to fill you in on past history. You will need to verify the facts cause sometimes non factual stories are handed down over the years. Join an online genealogy group that is researching the district /country that your descendants came from. Happy hunting.
