Hi -

You can start out by gathering what you do know about your family. Were Adam and Helen the generation that came over from Lithuania, or had it been their parents? Do you know if they had brothers and / or sisters? Yoou can find information by looking up where they lived on the various censuses, who else was in the family, and even who applied for citizenship. Where did they live when they came to the US? A few things to start with...
