Sure, and there are many sources available. I suggest that a good place to start would be your local library, for they always have information on genealogy and often have special sections with newspapers, travel documents and logs, and much more. The librarians will be glad to help and may even tell you about the local genealogical group that might even meet at the library, as does the one in my home town.
I could list many sites and companies that would do well for you, but lately the "spam-guard censors" at Yahoo! have been working overtime and might block the answer, so why don't you just put in search words for "genealogy" or "ancestry" or "family history" or various other words and phrases. You will find more than you could ever use. Some information is free and some requires payment.
The Church of Jesus Christ of Latter Day Saints (Mormons) have great respect for family history and provide a wonderful source of help, information, and inspiration. Look them up. Check with court houses, churches, and other institutions in towns and counties where you know your ancestors have lived. Do Web searches for the names, but be aware that there might be many people of the same names, so do narrow down your searches when you get to a good place.
Write letters to relatives, most of whom will be glad to help. There may be boxes of pictures and letters and newspaper clippings just waiting to be visited. You will be pleased at how much you learn and how you might even become closer to known relatives and learn about relatives you didn't even know you had. There are many, many, many routes to follow, but you won't regret it.
There are some scams and near-scams operating to take your money on paid services, so check out any paid services you might decide to use. Oh, by the say, there is a great Social Security Death Index available, too. They seem to be linked with a legitimate paid service to get full reports, but you can get good leads there without getting the full reports.
Hey, you are to be commended for pursuing this for and with your children and their children and..... Good luck.
