This has been a tip of the day before, but I believe it is important enough to occasionally be repeated.
Writing up your genealogy research is important. It will make you look more closely at what you have, your assumptions and your conclusions. Remember to write for someone who does not know anything about your family.
You might be surprised at the things you learn. And consider submitting your finished product to a local genealogical or historical society quarterly in the area where your ancestor lived. It is a great way to preserve your research.
And don't forget to cite your sources.
