FamilySearch's uploading of more than 14 million New York probate images from 1629 to1971 is an immeasurable boon to genealogists with research targets in the Empire State. It can, however, be immeasurably frustrating to find any particular person in the browse-only collection! It's divided by counties, and within counties by type of record and within that by volume or box. The boxed loose papers, organized by decedent, are among the most valuable probate records, and they don't even have page numbers!
Since I had to root through one of these virtual boxes anyway, in order to find my wife's ancestor William Berry, I kept track of all the other decedents whose estate papers had lodged in Box #2 from rugged Allegany County. The list of 67, with initial image number for each, is now on my web site. They are in order of appearance; if you don't have time to read all the names, use control-F to search them. They appeared to me to all be in the 1830s-1860s time range, where such records are most valuable. There are way plenty more materials in this one collection that would benefit from any sort of finding aid.
Here's a May 1845 summons to the next of kin of the late Gideon Hayward. James Hayward was living in Vigo County, Indiana, and Jane Davis nearby in Clay County. These are not just "New York records."
