Early Origins of the Oddonnell family

Migration of the Oddonnell family
Death and immigration greatly reduced Ireland's population in the 19th century. For the native Irish people poverty, hunger, and racial prejudice was common.

An examination of passenger and immigration lists has shown early immigrants bearing the name Oddonnell: Charles, Roger, Thomas, William O'Donald who arrived in Philadelphia, Pennsylvania between 1840 and 1860; Phillip O'Donel arrived in Boston Massachusetts in 1767.
