just a quickie as this is a useful tool if you dont already know it - the kind people on ancestry told me about this -
ok if you have a mistake for eg you put the wrong wife or whatever - you can delete the relationsip without deleting the person from the tree - you click on relationships for that person and remove whats not right the person will still be hanging on as a 'floating person' and you can then later add to a different part of your tree when its right but searching in the box - so if you add the wrong children you can re-add them as well somewhere else - particularly uselful if you had the wrong census and you added a whole bunch of children -
happy hunting
