It's so lovely when complete strangers take the time to get involved - I think we forget that our research is often interesting to other people too.
I recently wrote a 'To whom it may concern' letter addressed to the farm where my gg grandfather lived, not knowing if the property even has the same name after all this time.
I enclosed a translation of a Galar Gan (a Welsh poem of lament, written for him on his death) which talked about his great love of the land he lived on, and the stream that gave the farm its name. He obviously had a strong constitution, as he took a bath in the stream every morning, even when he had to break the ice first!
To my delight, I received a letter back from the current owners who found the poem deeply moving, and went straight outside in the snow and photographed the stream for me, so I now have a stunning photo of his outdoor bathroom, completely unchanged, and just as it must have been 120 years ago.
Always worth asking - you don't know what you'll get back, and wonderful results like these make the disappointments pale into insignificance!
