I've found them!

Last year there was only one cygnet .... this year Mr & Mrs have 9 babes to look after.

There is a little nature reserve at the far end of the Heritage Park loch but there is no access for the public. There is a gap through the trees but getting a good photo wasn't easy. The birds are safer in the reserve but in a day or two the family will swim out into the loch where they will join the goslings and their parents.
