Record Detective from My Heritage sounds intriguing. It can take one record and find many other records that are related. This is what they say:
Record Detective is a new game-changing technology from MyHeritage, which will provide you with many records, other records and tree profiles about the very same people. It is highly accurate and will not waste your time with false positives. It is original and there is nothing quite like it in the industry. It doesn’t replace manual research, but it can often help you save time and find relevant information you may never have found on your own. A summary of any record may be viewed for free.
Of course it is all subscription based. Although is says that summary is free it isn’t much of a summary from what I’ve found, but it may be useful for people who want to spend the money.
