Gathering physical evidence brings the guide to life and provides verification for future generations.

Create dedicated digital or physical albums. Use platforms like Facebook Media Sets to share and identify photos with other family members.

Note if the family moved (e.g., from Indonesia to the Netherlands) as this often explains gaps in records.

Include formal names used in official documents and any "call names" or family nicknames (e.g., "Oom Penk" or "Tante Prul").

Document their professional lives. Were they academic types who "kicked it far," or more hands-on "do-types" like gardeners or experts in specific fields?

Record dates and places for births, marriages, and deaths.
