AFAIK the untranscribed Braddan register covered the years for which both New and Old yards were in operation (and AFAIK didn't cover St Lukes at Baldwin) - I'm currently back in Peel and will check, as my information came from Priscilla when I told her of the 2 pages missed from the official transcript.
I have a copy of Foxdale back at Guildford - I was given it by Noreen some years ago so it might well be a draft version.

The Atholl street was listed in an article which is on my website but only about 12 burials - however the register should now be in Manx Museum.
