Birth & Marriage Certificates are available from
The Registries, Deemsters Walk,Bucks Road, Douglas, Isle Of Man, British Isles,1M1 3AR
They do not take Bankcard and as International money orders and bank drafts for a small amounts of money are very expensive from Australia, I obtained a Ten Pound note from my Bank and attached it with my request for a Marriage Cert. early this year and received same within a month.
For North of England try General Register Office Po Box 2 Southport Merseyside PR8 2JD
They do take Bankcard. Tricia Paterson of the Family History Team was very help full.
