As my planner fills with more group sheets, I occasionally need a 4 gen chart to help me visualize who belongs to who. I don’t need a ton of these, so I put a group sheet on half of the page and the 4 gen chart on the other half. I don’t think any instructions are needed except to say that if you highlight the person title (“father”, “grandmother”, etc.) then you can type in the name to take it’s place. Put your curser after the b. m. or d. and type in the desired date and/or location. The arrangement is a little different to make 4 generations fit for both a husband and a wife, but I think it’s easy enough to fill out.
