Re: HELP !! Where would I find probate in 1826 for OAKLAND COUNTY ?

I'm not sure of the exact beginning dates, but the County Probate office does have old microfilm records.There is a binder index located at a side table where you can look up the reel # and a records office clerk in the back will retrieve the film for you to view.I found a relative's probate file from 1850 that way.
Family Search.org does maintain an index where you can check the name.
