Henry Puxley was orchestrating a new addition to the
mansion when his wife died in childbirth. He was so distraught by

The meanest of the Sullivans there was
probably “Wild Bill” Sullivan in the early 1900’s:

some say as many as fifty, although seldom could anyone name a victim. Others said he was the meanest son-of-a-gun
that ever walked the face of the earth and that he took his
as the tyrant of the valley. His mother called him lead-proof, the clan
him wild, and his enemies called him everything their imaginative ire
think of. He drank heavily and brawled
weeknights as well as on Saturdays, fouling the air with curses and
was generally agreed that few blacks were welcome in the
Hollow. Once Wild Bill Sullivan caught a
black man, he would tie a bundle of bobwire to his back and make him
on all fours and crawl a mile, before telling him to leave the Hollow.

The Irish clan or sept names come through the mists of time until they were found in Irish records such as The Annals of the Four Masters. The names were Gaelic and this Gaelic order was preserved until it was battered down by the English in the 1600’s.
Some made peace with the English. “Wild geese” fled to fight abroad. But most stayed and suffered, losing land and even the use of their language. Irish names became anglicized, although sometimes in a mishmash of spellings. Mass emigration happened after the potato famine of the 1840’s.
Some surnames – such as Kelly, Murphy and O’Connor – span all parts of Ireland. But most will have a territorial focus in one of the four Irish provinces – Leinster, Munster, Ulster, and Connacht.
Munster in SW Ireland covers the counties of Clare, Cork, Kerry, Limerick, Tipperary, and Waterford. Here are some of the Munster surnames that you can check out.
