Can I get an Irish passport?

French Huguenot refugees on both sides
Too far back to be useful

I would require dual nationality though (hedge my bets)

I don't know, Jalima. I spent years on my family history and couldn't find anybody who was even vaguely non-English and I got back to the sixteenth century on almost my lines.

I think there will be a deluge of new Irish citizens!

Looks like I will be trying for a Scottish passport

I have an Irish grandfather and I have decided to apply for Irish citizenship. I have all the necessary birth and marriage certificates but if you do not have these you can get copies from the relevant country registrars.

How far back can we go?
(French Huguenot?)

Unfortunately, I only have English ancestors.

Can I renounce my nationality and become stateless? Maybe somebody will adopt me.

I thought my Grandfather was born in Ireland , but he was a Glaswegian !

yes you can , you have to have birth certs marriage certs etc
