A search for Shinn cemetery came up with 391 pages Other examples for useful genealogy source searches might be words deed and will. Since both of those have meanings other than what is used in genealogy, the results should be expected to be mixed with non-genealogy pages. For a search of Shinn deed 141 pages were found and a fairly good number of them appear to be genealogy related. This shows that some words that would aotherwise be very helpful, can t be depended on because they are just too common. However, there were only 19 pages found and every one of them had the exact phrase last will and testament.
Some searches can produce surprising results.
For example, one of my surnames that is connected to the Shinns is Lippincott. Initially, many people would not expect that that name would result in a lot of pages being found. Part of the reason for this is that Lippincott is part of the name of a publishing company, so pages with citation for the publisher appear. However, when I combine the two surnames that I have used here, better results should appear. In fact, with Shinn Lippencott there are 13 pages listed.
