Do you remember the book Roots?
Genealogy research became more popular with the publication of this book by Alex Haley in 1976. Do you remember the TV miniseries in 1977 based on the book...it was very popular and genealogy research became a new quest for many Americans. (The libraries have both the book and the video of Roots.)
I've added the link to a new online database. (Funds for the subscription are from a grant from the Florida State Legislature.) This new online source of information is Ancestry Library Edition linked from our main web page. There is no remote access from home (the company does not sell remote access) so you must use library computers to search the database.
You will find information from the 1930 U.S. Federal census, ship and passenger immigration records, and even United Kingdom census information. There is more information and the database is updated daily. The searching is easy and you can print information, email it to yourself or others, or save your information to a disk.
The libraries have many books on genealogy, some you can check out, some to use only in the library. Look in the 929 section or ask a staff member for help.
