The chain decides the list

Add yourself, your parent and the ancestor your claim runs through, with the events of each life. A marriage adds a marriage certificate; a naturalisation abroad adds its record and a date check.

Mismatches found early

Hanlon on one record and Hanlan on the next, a day and month swapped, Queenstown and Cobh. Each mismatch is listed with the two documents it comes from and a note on how you resolved it.

Family data never leaves this browser

Names, dates, places and references are stored only in this browser. There is no account and nothing is uploaded; documents themselves are never stored, only where the paper is.

Countries and routes

45 rules, each with its source, edition and the day it was read. Rules we could not confirm at a primary source are shown as settings to check, never as facts.

How it works

  1. Pick the country and the route from the lists.
  2. Add each person in the line and what happened to them.
  3. Work through the register: request, receive, apostille, translate, check.
  4. Print the missing list, and the document index when you file.
