Irish Birth certificates

[Blackrose87]

After reading comments from people on this forum, I decided to do a bit of research into my family history? I'd really like to be able to trace my family back to their departure from Scotland.

I've been looking around today and so far I've traced back to my great-great-great-grandfather on the 1901 census who was apparently born in 1822. ( Didn't take too long as the family has moved from the same town until my father moved to Derry)

Are there any good websites to find birth certificates from around the 1820s? Or something else to find his parents?

I know Irish records are hard to find from this time, but can anyone point me in the right direction?
