The Clan/Sept History

The Irish name O Crean has a long Gaelic heritage to its credit. The original
Gaelic form of the name O Crean is O Croidheagain, from the word "croidhe,"
which means "heart."

Those scribes in Ireland during the Middle Ages recorded names as they sounded
simply because their bearers were illiterate. Consequently, in this era many
people were recorded under different spellings each time their name was written
Down. Research on the O Crean family name revealed numerous spelling variations,
including Cregan, Crean, O'Crean, O'Cryan, Creaghan, Creegan, Creahan, Crehan,
Creane and many more.
First found in Donegal, where they held a family seat from ancient times.
Thousands of Irish Families left for North American shores in the 19th century.
These people were searching for a life unencumbered with poverty, hunger, and
racial discrimination. Many arrived to eventually find such conditions, but many
others simply did not arrive: victims of the diseased, overcrowded ships in
which they traveled to the New World. Those who lived to see North American
shores were instrumental in the development of the growing nations of Canada and
the United States. A thorough examination of passenger and immigration lists has
disclosed evidence of many early immigrants of the name O Crean: Phillip Crean
who settled in Philadelphia, Pennsylvania in 1860; John Creahan settled in
Philadelphia in 1868; Thomas Creane settled in Philadelphia in 1868.

Motto Translated: Create in me a clean heart, O God.
