Where should you start looking?

Casualty records anchor a timeline with the fact, date and ship or place of loss. Use them to close a timeline, then work backwards through ship postings.

The strongest first check is a boring one: does every filter agree, or does only one agree and the rest stay silent? A name spelled one way in one record and another way in the next is the same research problem wearing two spellings. Collect the variants before you search. Two people with the same name in the same unit are not an edge case. In large units they are the normal case, and the number is what separates them.

How do you read what you find?

An entry that flatters, an entry that blames, and an entry that is purely routine are written for different readers. The reader shapes the wording. A date written in one format on one sheet and another format on the next is the same date wearing two formats. Convert carefully, and keep the original.

A name in a unit document proves presence only when name, rank, role and dates all match the person you are researching, not when the surname alone matches. A word that looks familiar may have meant something narrower, or something entirely different, when the record was written.

Dead ends to expect here

If every search returns the same wrong person, stop searching and re-examine the filters. Repeating a search with the same filters will repeat the same result. A record set described as complete usually means complete for its own purpose, not complete for yours. Check what the set was made to record.

Each dead end here is a normal research outcome, not a personal failure, and each one points to a next check rather than to a conclusion. If the trail ends at a particular holder, the next step is to ask that holder where the record went, not to search the same catalogue harder.

How do you work through it step by step?

If you are unsure which step comes first, choose the step that fixes a date. Dates order everything else, and an unfixed date disorders everything else. Write down the step you are on, in plain words, before you take it. A step you cannot state plainly is a step you do not yet understand. A note made at the time of reading is worth ten notes reconstructed at the end of the session, because memory edits as it reconstructs.

StepWhat to do
1Fix the service dates first, so you know which holder is likely to hold the file.
2Note the service number and the rating or rank together, exactly as written.
3List ships and shore establishments in date order, and treat each draft as a separate check.
4Test every later record, log entry or casualty entry, against the personal file before adding it to the timeline.

Where to go next from here

Let the question this record raised choose the next record. A record opened out of curiosity, rather than out of a question, rarely advances a timeline. The end of a guide is a good place to review the timeline for unreferenced entries. Remove them, or mark them, before they harden into facts.

Where this record and another disagree, the next record should be one that can explain the disagreement, not one that repeats one side of it. If this guide has made the next record obvious, it has succeeded. Go to that record, and take the question with you.
