ANECDOTE

47-Page Probate File Breakthrough

  • Brian avoided a 47-page 1892 probate file for three years because legal jargon and volume overwhelmed him.
  • After uploading it to Google NotebookLM, he gleaned the key dispute in 20 minutes and found the story he'd missed.
INSIGHT

NotebookLM Uses Only Your Documents

  • NotebookLM only knows what you upload, so it answers from your documents with citations rather than from broad internet-trained knowledge.
  • That prevents hallucinations and makes it ideal for proof-focused genealogy work.
ADVICE

Organize Notebooks By Family Line

  • Organize notebooks by family line or research question, not by document type when creating a new notebook.
  • Example: name a notebook "Smith Family–Ohio" instead of "Census Records" to keep context together.
