I want to obtain a copy of the original naturalization document as referenced on Ancestry.com. for George PURVIS, 1836-1837.

Source bibliography:
An Index to Indiana Naturalization Records Found in Various Order Books of the Ninety-two Local Courts prior to 1907. Indianapolist: Family History Section, Indiana Historical Society, 1981. 172p. page 124

Can someone tell me how to get a copy of this naturalization record?

Thank you,
Susan Holley
