I am currently inputting a long and involved family history which, particularly where there are cousin marriages does involve some duplication of listings. The reason I ask the question is that yesterday the system failed to pick up what I would regard as a fairly obvious match; the surname was the same, the forenames similar, although some change of order and for one name a different spelling, date of birth was identical and although one was more detailed, places of birth etc. were identical. I immediately merged, although in hindsight it may have been more useful if I hadn't but I do wonder if the issue needs looking at.
On a second point the family history that I am entering contains a lot of extraneous, if interesting material about the Bangert family and I wondered if there was anywhere that this could be written up. The history is a fine piece of work and was written in German in 1932. As far as I know, I am in possession of the only English translation running to some150 pages.
