Ancestry's news item today regarding the re-launched UK directory collection states: "We've recently improved our OCR technology, and re-scanned all the hundreds of directories in this collection. That means your search results should be more accurate, and you should find it much easier to spot your relatives on the results page."
But anybody listed in a directory with an initial rather than a forename, has had their initial replaced with a forename of Ancestry's choosing! So for example E becomes Edward, G becomes George, J becomes James and T becomes Theodore. Exactly how this is supposed to make search results more accurate, or make it easier for people to spot their relatives on the results page, is beyond me.
