I stumbled across a treasure trove of estate documents at the Family Search centre some time ago but only now figured out how to access some of the Ripley documents. The files may include wills, inventories, dispersals, receipts, and other probate documents. Some of the wills have shed light on the Ripley homesteads, confirmed paternity, and even turned up previously unknown children.
There are many more volumes to explore but here is a list of the Ripley wills I have found so far in the four volumes I looked through. Although the filing system still makes no sense to me, the quality of the scans is excellent. I've put the list of Ripley Wills Online under the resources tab. Enjoy!
