It's difficult for anyone to assist you without any of the following that you might know:
Location - Country > Province/Region/State/County - City, town
Dates or approximate dates of birth, marriage, death
Add any names of additional family members including any spouses, parents, siblings, children.
A good place to start is familysearch.org and use their search tool at
https://familysearch.org/
where you can plug in names, location, date ranges etc. to see if your ancestors appear in any of those free online records and then work from there. These searches and results are FREE!
Good Luck.
