Hello Ira and others, I have here a database which grew up to around 4800 individuals.... From time to time, I have problems when either making "big" imports (GEDCOM imports) or connecting two existing individuals. For instance, if I want to "marry" two existing individuals by using the standard method for doing so (+Conn/Connect a Spouse), both individuals get a new "marriage" '1/1 on the left of their name), but they are not shown together. I can add a marriage event to both, but no story shows up then.... If I make an index rebuild, individuals are disconnected again.....(sometimes this has corrected the problem, though). Then, the only way to connect them is by adding a new spouse to one of them and then merge this new individual with the real spouse.... On the other hand, I sometimes find couples who have "lost" their children (I make index rebuild quite often, thus cannot tell when it really happened). What can I do? Do you, Ira, have additionnal tools for checking database integrity (and should then I send you a zipped versionof my database?) What if I make a full GEDCOM export then import? What would I lose then? --
