O'Dooly History, Family Crest & Coats of Arms
While many Irish names are familiar, their past incarnations are often shrouded in mystery, reflecting the ancient Gaelic heritage of their bearers. The original Gaelic form of the name O'Dooly is O Dubhlaoich, derived from the words dubh, which means "dark featured, great, prodigious, burned" , and laoch, referring to a hero or champion.

Migration of the O'Dooly family
Suffering from poverty and racial discrimination, thousands of Irish families left the island in the 19th century for North America aboard cramped passenger ships. The early migrants became settlers of small tracts of land, and those that came later were often employed in the new cities or transitional work camps. The largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s.

Early immigration and passenger lists have revealed many immigrants bearing the name O'Dooly: Lawrence Dooley settled in New England in 1774; followed by Bernard, Daniel, Henry, James, John, Martin, Michael, Steven, Thomas, William, who all arrived in Philadelphia between 1840 and 1870..
