Behold will help you find many different types of problems with your data file:
Non-Standard GEDCOM: There may be something wrong with the GEDCOM file that does not follow the GEDCOM standard. Behold will detect these problems and report them in the log file. Normally, they will not be of concern to you, because Behold has no problem reading this non-standard GEDCOM. But it may be of concern if you are trying to load your data into another genealogy program. That program may not be able to properly read some or all of the lines that are reported.
Data Problems: There is something wrong structurally with your data. These are reported as "Data Problems". These are items that you will be interested in. You should look for these and fix them when they appear. Behold, by default, will display a line in the heading of the Everything Report to make you aware that there is a data problem. The line will appear just before the Table of Contents title and will look like this:
If this occurs, click on the filename and the hyperlink will take you to the File information for that file where you can see a summary of the problems.
Ancestor Loops: Behold is one of the only programs that can find ancestor loops (where a person is their own ancestor) and let you know about them in a way that will allow you to correct the problem. An example of an ancestor loop message is:
Notice that the individual ID numbers are listed so that you can tell the people apart and try to figure out which parent/child connection is incorrect.
Unconnected People: After selecting the person of interest, the "Everyone Else" section are the unconnected families, and the completely "Unconnected Individuals" are given their own special place among the Everyone Else. You may see families or people here that should be connected, so now that you know about them, you'll be able to correct them as they should have been.
Duplicated People: Sometimes, especially if you've used some program to merge multiple data files together (highly NOT recommended), your file may end up with duplicate entries for the same person. To find those, go to the name index. Scan through the index looking for two people, one after another, with identical or near-identical names. They could be people that are repeated. The birth and death dates after the people will be additional help. Behold will make it easy for you to go back to their data and see if they are the same. e.g.:
In the above example, the two Heinrich Richard Niefts are probably different people, but the two Heinz Richard Nieft are probably the same and may also be the same as the Heinz Nieft.
Unreferences Sources, Repositories, Notes or Objects: Behold will list all references to any sources, repositories, notes or objects. It will indicate those that are unreferenced. This may be okay if you entered one of these items just to remember it, but these usually are referenced from individuals, families, or events within them. Behold helps you identify these.
Inconsistencies: These are slight differences in the spelling and use of surnames, placenames, and source references. You can find these by scanning through the Name Index, Place Index, and Source Index. They will pop right out at you.
The Log file contains all the problems Behold has found with each of the GEDCOM files input. You can open the logs files by selecting "View Log File(s)" from the View menu, or by clicking on the Log item on the Toolbar:
Logical Problems, also known as a Sanity Check: These are contradictory event dates. Children cannot be born after their parents, or when their parents are younger or older than certain ages. There are many possible checks here.
This version of Behold does not yet do these logicals checks. They will be added at some time in the future, possibly for or just after Version 2.0.
