Bagge Ancestry

I wonder if anyone can give me some advice?
I am researching my family history and I would like to know where I can locate Isle of Man records on-line.
I live in Spain and therefore need to do most of my research online.
I know that my Great Grandfather and his Brother were born on the Island (Douglas, I think). Their surname was Bagge. Herbert was born c.1870. Harry or Henry was born to the same parents but I would think 1890's.
If anyone can point me in the right direction, I would be most grateful. I do not have anymore info to work with.
Many Thanks and Best Regards...
