Hi Alan,
welldone on your project, we wish you all the best with it. To find family members you might be better-served writing to the local newspapers.

Meanwhile it would be a great help if you could provide the names of those on the Memorial, I've tried looking online but no luck thus-far.

eg the photos here are not too clear.

Sorry, beg your pardon, the names and a fair amount of background material about each of these brave men can be found at the end of this webpage.
