First of all if you have a name and parents you could post this. You may find information through other sources.
1. Try census records. Familysearch.com has census records
2. Other sources, marriage, death records, Military records, also look for these on familysearch.org
3. Check to see if they had siblings and this might give you a clue
4. Look for late registrations if the place has them
Best wishes in your research.
4. Look at familytrees and see your family name, etc.
