I am trying to locate a possible will or probate records for William or William W. Rooker, who d. ca 1837 in Brown Twp., Morgan Co., IN. He was widowed; in 1820 he was granted 80 acres from the gov't (T13N, R1E, Sec. 12, E 1/2 NE 1/4). I need to prove the relationship of his daughter, Mary/Polly, to him. Any help would be appreciated.
