I am seeking information on William Collier of Fayette County, Illinois who was somehow related to Thomas Naran/Narron/Naron. Would like to know the relationship to Thomas Naron. Letter to Probate Judge is as follows:

I, William Collier of the County of Fayette and State of Illinois being the only relative of Thomas Naran, late of said county and state aford said dec. (except his infant children) do hereby relinquish all my rights as said relative to administrate on his said estate and as said estate is likely to be distroyed it is my last request to grant that Nelson Real (Ryal) of said county of Fayette and state afore said___ be approved. Adm. of said Thomas Naran dec.
To the Probate Justice of the peace for the Court of Fayette and state of Illinois. Oct. 26, 1837 William Collier

Any information on William and his family would be great appreciated.
