Ok I did one letter, from a woman in 1814 writing to James Monroe (then Secretary of State) asking for a passport to go to Scotland to get her late brother's property. What a trip! So enjoyable to get into the flow once you've "synchronized" with the persons handwriting. Furthermore, due to the fact that you're reading and re-writing word for word of whatever you're transcribing, the stories you end up reading have tremendous memory-stick. This is not surprising, considering that you are dedicating an inordinate amount of time per page, but it's a welcome side effect when you try and recollect.
