Despite being very Irish with a Very Irish voice,

My parents were both born in Ireland, my Grandma had a heavy accent, my Grandpa and Dad kinda do, my Mom doesn't. I wish I did though...

Yes, I'm very irish, while not born in that great country, I have many grandparents and great grandparents of Irish descent. While not a full blood due to having one great grandfather being half Irish and half french and a great grandmother being a full blood Native American, I can say that voice speaks with the Irish tongue through and through.

I haven't had an Ancestry test but my great-grandpa was Italian from my Dad's side my Mom said. I think the majority of from Ireland. My voice is deep and kind of gravelly and I have a bit of a lisp. Some people do think I have an accent.

Your accent might be deep like mine, not always do we Irish speak with such a high voice. The best note is the way certain words and letters come to you. Listen to some Irishmen and see if they make the same vowel and tone usage as you, no matter the lightness or deepness.
