There are times where all a person needs is a snippet of material from their database to help remind them of key details on a family or group of individuals.
When working on an aunt, ,her two marriages, and her husband’s two (or three?) marriages, names and dates were running together. I did not need all my data in front of me while searching. I did not need an extensive chronology in front of me. I just needed the key marriage dates and names to keep myself from getting confused and having to constantly refer to my database.
The little chart is not comprehensive. It is not cited. It is for my use only to keep me from getting totally confused.
