Thanks but no thanks. I think I'll pass.
You don’t need to ‘claim’ citizenship, it’s automatic:
“Born outside Ireland?
You are automatically an Irish citizen if one of your parents was an Irish citizen at the time of your birth and was born on the island of Ireland. You don’t need to apply to become an Irish citizen in this case.”

Anyone born on the island (before 2005) is an Irish citizen and can apply for a passport without apply for citizenship separately.
This was the route that I went down. Both parents born on the Island of Ireland made me automatically an Irish citizen. I simply applied for my Irish passport.
