History of the Irish name O'Sullivan

Sullivan Name Meaning, Origin, History, And Popularity

Tracing your Irish ancestry - The O'Sullivan Clan

If you see spelling variations, that’s not the same as what we think of now as a name change. Consistent spelling is a modern concept. You will see lots of spelling differences, but what you will not see is someone arriving at Ellis Island as a Sullivan and being told their name is now Henderson. Names were not changed. No one was asked to spell their names. There was not a language barrier. #ancestry #genealogy | The Formidable Genealogist
