I had online online classes today and I got a bit bored (3 hours of listening about minimalistic art) so I decided to do some genealogy research at the same time. I was reading some articles about my relatives and editing my family tree. My tablet started lagging (the screen went black randomly a few times) so I closed most of my apps and only left MS Teams, Google and MyHeritage on. But it didn't work so I ultimately closed MyHeritage too (It seemed to be the most likeable reason for the lag). It didn't work and everything started lagging again, but this time for a split second an unknown photograph appeared on the screen. There was a man (I guess around 60 years old, with a white beard, wearing a suit) standing on the left side and a date 1877 on the right corner (I'm attaching a drawing of what this photo looked like). I have various old photographs in my collection and I don't recognise this one at all. I would ignore something like this but the place that I'm in is rumored to be haunted. My family says that after my grandfather's death in 2009 his spirit came to check if everything is alright in his hotel for a few years. But this photograph can't be him since he was born in 1948. There are also some WW2 german soldiers buried nearby and who knows, maybe someone else too. I have no idea what this means, I wanna hear some suggestions fron you guys.
