Migration of the O'Shirren family to the New World and Oceana
In the mid-19th century, Ireland
experienced one of the worst periods in its entire history. During this decade in order to ease the pressure of the soil, which was actually depleted by the effects of the previous years' grain crops, landowners forced tenant
farmers and peasants onto tiny plots of land that barely provided the basic sustenance a family required. Conditions were worsened, though, by the population of the country, which was growing fast to roughly eight million. So when the Great Potato Famine
of the mid-1840s hit, starvation and diseases decimated the population. Thousands of Irish families
left the country for British North America and the United States. The new immigrants were often accommodated either in the opening western frontiers or as cheap unskilled labor in the established centers. In early passenger and immigration lists there are many immigrants bearing the name O'Shirren: Daniel, Edward, Hugh, Patrick and Thomas Sheerin who landed in Philadelphia, Pennsylvania between 1804 and 1864; Edward and John Sheering landed in Philadelphia in 1867.
The O'Shirren Motto
The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Vincit Veritas
Motto Translation: Truth conquers.
