Great presentation; just had a first quick look. My grandfather moved into what is today, Barry O'Dwyer and Holly Breen's house, in 1907 and I was born in this house as was my father in 1912. That house is nearly 200 years old as is indicated by a little kink in the rear Boundary which is clear in the earliest 1834 street maps. It's very interesting to look at that earliest Rosse photograph as it suggests that the two lower houses to the right of 'ours' were higher at Crotty's side than they are today. The party wall between our house and 'Barrys was always strange as Barry's chimney breast is within our wall where there are and never were fireplaces. Will study this presentation carefully ....Thanks to all concerned.
