Undated family photos can be organized provisionally without pretending to know the exact year. Separate evidence from guesses.
A practical way to begin
Look for readable signs, known buildings, inscriptions and links to other dated photographs.
Ask relatives independently what they recognize before offering your own theory.
Record a date range and the reason for it instead of selecting one unsupported year.
Keep unresolved photographs together so later discoveries can be compared.
For example
If two relatives recognize a house occupied during a known period, use that range and cite the household information in your notes.
What to avoid
Clothing and hairstyles can suggest a period, but they do not prove the date. Avoid overwriting an earlier label without preserving it.
Should I keep the original material?
Yes. Keep an untouched source and work with copies. A finished album, transcript or edited video serves a different purpose from the original material. Check that your saved copies open, and keep important context such as names and dates alongside them.
