Sullivan
We claim Ulster Scot
Erroneously prolly given Sullivan is third most common name in Ireland ...
They became prods at some point....
And I’m pretty sure they were O Sullivan’s before they dropped the O and their Roman past....just guessing
Sullivan’s Hollow Mississippi but originated in Virginia 1720s after coming from Norn Iron

It’s disputed the origin origin of the Red Hand but it’s been associated with the northern counties around 700 years and used by many Ulster organizations
Legendarily the O’Neills were first to claim Ireland when Heremon O’Neill lopped off his own hand and threw it ashore. My paternal great grandmother was a Neal, which was O’Neill going back a ways.
Legend has it the bloodied hand represents the dismembered hand of the captain that laid claim to the land discovered (or commandeered.)
If from Ireland, your 1720s heritage definitely precedes the U.K. bondage.
