Make your site user friendly!

just joined your site and have started to add my information, now I see that my grandfather is the son and my father is the father and the grandmother is married to the son,  Bit confusing?  should be able to fix this simply, but no can do, so before I commit to paying for  this I need to know if this is an ongoing problem or will you at sometime in the near future create a way of changing-not deleting- information and as for asking Francis (the Grandfather) for permission to delete some information I would have to consult a medium, Know any good ones?   I already have been through the edit  but that didn't work do you have any other suggestions.            Maree
