Dear Jim.
I have been reading Lisburn Exiles Forum, it is the nearest I can get to Derriaghy.My primary interest is
Lagmore Reservoir. My grandfather Anthony Watson worked there until he died suddenly in 1938 when his son,also Anthony but known as Tony took over the running of the dam as it was known. He was there until the late 70s. I wonder if any of your correspondants know anything of the history of this place.I was born there and later lived on the Barnfield Road but moved away when still a child.I would appreciate any information. Iknow the dam has been built over and is history now, but it played a large part in my childhood. Many thanks for your site.Gladys Hudd nee Watson.
