Searching the family surname can be a good way to determine if part of your family tree has already been constructed. The New York State Library has many tools which will help you search for surnames.
Surname card file (Genealogy Area) - This indexes genealogies owned by the New York State Library in a variety of formats: books, articles, pamphlets, manuscripts, Bible records and segments of larger works. Genealogies in book form that were acquired by the Library after 1980 are not indexed in the card file. Use the online catalog instead.
Excelsior Information Online - The State Library's online catalog has information about books and microform genealogies in the Library's collection. Enter the surname (try various spellings) and the word "family." Click "Search Everything."
Periodical Indexes - Family genealogies printed as articles in genealogical magazines can be accessed through genealogical periodical indexes. Look up the surname. Copy the journal title, issue, date and pages where the genealogy appears and then check Excelsior to see if the State Library owns the journal. Type the title of the journal and click "Title." If you cannot obtain a copy of the article at the State Library or directly from another library, you may wish to submit an interlibrary loan request at your local library. To do this, you will need the article's author and title, the title of the journal, the issue, date and pages. You also need the title, volume number and page of the index where you found the information. The following indexes may be helpful:
