I've had 2 stubborn people who won't believe what's been proved by documentation.
I looked for my 3rd gt uncle's marriage. I found he went 7 miles from his home town and married a neighbour's (previous census) daughter and he was a locksmith like her father so they may have even worked together. I may never understand why that church was chosen.
Three people have queried this finding. Two e-mailed straight away, both saying they had discounted that marriage because of the distance from where he lived. I told them what I knew about the area and travel in the era as I was born in the same area - the two ladies were in Aus and NZ. I must admit I did a copy and paste so they had the same e-mail. The NZ lady thanked me and told me I had brought history alive for her. The lady from Aus more or less said it was impossible to move about then and I'd written bunkum. Incenced I sent for one of my 3rd gt uncle's sons birth cert. (wouldn't have to do it today) and I downloaded the cert. to my tree. I then told both ladies what I had done and the MMN - it was easy on that son as he had a very uncommon name. I stated it proved the marriage I had on my tree. NZ lady thanked me - still waiting for the Aus lady
. Another person queried it about a year later so I refered them to the son and his birth cert. and got thanked.
The other was even more frustrating. I received an e-mail stating I had killed off her gt uncle in WW1.
She said there were 2 (am putting in substitutes for names and places) Fred Bloggs (distant cousins) in the same local regiment, one died and one survived. Her gt uncle from the village XYZ had survived as her parents would have told her if he'd died. The Fred Bloggs from the nearby town of ABC was the one who died in WW1, her gt uncle died 1960 in ABC, perhaps in the local hospital.
I wrote back that I had only put the death in when I'd check the soldier's effects where the NOK was shown as Fred Bloggs's father from the village XYZ. I also said it was my Fred Bloggs death 1960.
She came back with I was still mistaken and I had made a mistake putting in children to the 2nd Fred Bloggs after WW1 as they couldn't exist with him as the father.
I wrote back if they didn't exist to that Fred Bloggs then my mother, her siblings and even myself didn't exist as Fred Bloggs was my maternal grandfather and I'd been there at his funeral as a child in 1960. For some reason she never replied.
I have been corrected on my tree, I don't believe straight away, I do double check. I have found the mistakes and altered them and thanked the person for letting me know. I don't copy from other trees directly, I do my own research but if it's their branch of the family I always hope they have a correct link up with my branch and it then becomes a happy addition to my tree.
