Naturalization Records in County Clerks' Offices
New York State courts that performed naturalizations during the nineteenth century included the county courts of common pleas (pre-1847); the county courts (post-1847); the Court of Chancery; the Supreme Court; the higher city courts in New York, Brooklyn, Albany, Rochester, and Buffalo; and (rarely) the county surrogate's courts. After 1906 only the New York Supreme Court could perform naturalizations, and in most counties it has ceased doing so.
