These answers are helpful but let Ancestry.com off the hook too easily. At 300 bucks a year, they need to get ths right. There is no reason that updated records should appear as hints with blanks that lead to even the 'opportunity' to select duplicates. Why are not the most likely matches displayed in all cases? And I'm sorry, but when you are going back several generations, often you are learning about these folks for the first time. So there is no way to know who is correct and who is not. That's what I'm paying Ancestry.com for -- to discover these folks. And in those cases where a duolicate does occur, then they need to provide a tool as a standard option to allow merging duplicates. These features need to be provided ASAP.
