A family of Microsoft word processing software products for creating web, email, and print documents.
While Word may not be the best application for this purpose, two avenues you can investigate are:
- An Organization Chart (Insert | Illustrations | SmartArt | Hierarchy)
- A table. This is very fiddly, but you can make it work either top down or side to side by merging and splitting cells and applying borders selectively. It's a little more flexible about adding text than the OrgChart as well.
There are also fillable PDF pedigree charts available online. The one I tried to use I found a bit Procrustean, but it is usable. You can find free ones at https://www.ngsgenealogy.org/free-resources/charts/, and a Google search for "fillable pedigree chart" will turn up many others.
