They have to be there. We have entered all the information we have. We have double-checked the facts. Everything adds up. Maybe we are entering too much information.
Databases are picky things.
They only pull up results for exactly what we put in. It may be that something as simple as a variation of the given name is holding us back. If you have entered a date of birth or date of death in the search, you may also be hindering the results. If you enter the entire date you are ruling out entries that only have January listed, not to mention any entries that may be listed with the wrong date. Locations can be tricky too.
