Happens all the time on my spirit box sessions. Get names that have zero connection to the location, no record of anyone by that name ever being there, nothing in the history books. Most people jump straight to "residual energy from somewhere else" or "the spirit travelled" but honestly I reckon a good chunk of it is just radio bleed and our brains doing pattern recognition on white noise. We're hardwired to hear names and words, its what we do.
That said I had a session in an old colliery building last year and got the name Margaret repeated three times clear as anything. Checked every record I could find, nothing. But my mate who came with me went white as a sheet - his nan was called Margaret and she'd died the week before. Make of that what you will.
Anyone else got examples where the name meant something to someone present rather than the location itself? Curious if thats a pattern or just coincidence.
