The most difficult challenges involve entries that seem to be potential duplicates but contain little or no distinguishing information. Mr. and Mrs. Jones may be a duplicate of your ancestors but without enough information to properly make the match, you have to pass them by as "Not a Match."
One notable thing about spending a lot of my time involved with helping others with their genealogy is the extremely small impact a monumental change such as the upgrade of the FamilySearch.org website has on most of the people. I am not talking about those who have no interest in genealogy. I mean the volunteers and missionaries at the Brigham Young University Family History Library. This observation is not a criticism, I merely observed that very, very few of the people I talked to last night at the library were even interested in the change over enough to look at the program.
Part of the challenge of working through the duplicates and conflicting information on the Family Tree is that relatively few people are actually working on correcting the entries. For example, I am watching 126 people right now. I find that 21 of those on my watch list have been "deleted," probably through merges. But on any given report from FamilySearch on the changes, I have made the vast majority of all the changes.
What happens as I do research into any given family line is that by adding sources and correcting the information displayed in the Family Tree, such as standardizing dates and places, the results produced are more potential duplicates. The piles of things to do just got bigger.
How do we approach this potential task? Well, we can ignore it like most of our relatives or we can start digging in and making the corrections, doing the merges and cleaning up the entries. I suggest methodically working your way back through your ancestral lines, just as you would systematically weed a garden or water your plants. I have been saying for years that I would be working on the Tanner line once the Family Tree program was fixed and now I have started. Of course, the Tanner line contains Parkinsons, Stapleys, Bryants, Shepherds, Stewarts, Rays and huge number of additional lines so it will probably take me a while to get around to all of them.
