William D. Osborn(e)

I am in need of a will or cemetery record for William D. Osborn(e)who I believe died between the 1860 and 70 census.I found his family in the 1850 and 60 census, but in the 70 census his wife Elizabeth (I believe Davis) was listed with her children.I would greatly appreciate any help.William D. is my gggrandfather.
Thanks, Pauline
