An experience !
1. Are you related to John Smith, his wife was Mary. (I replied, please provide some dates, places, children ... you all know the usual proper questions)
2. My John Smith was born in 1703 and he married Mary in 1707. She was born in 1709. They had 38 children and then Mary died in 1692. (I replied, those dates do not make sense, cannot see any possible connection)
3. Are you sure you are not related to my John Smith. (I tried explaining that a person cannot marry AFTER they have died, and noting the bride and groom were very young)
4. You are wrong, they married young in those days. Lots of people died in 1692. (Silly me, I tried again)
5. You are still wrong. Mary died, then John died, then their kids died. (I tried once more)
6. Certificates are only pieces of paper. You need to have your head read. (I decided to stop trying)
Any wonder I don't have any trees online anymore !
Cheers, JM
