Migration of the Longment 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. Therefore, thousands left their homeland to seek opportunity in North America. Those who survived the journey and the quarantine camps to which they arrived, were instrumental towards building the strong developing nations of the United States and the future Canada. By far, the largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. These were employed as construction or factory workers. An examination of passenger and immigration lists has shown early immigrants bearing the name Longment: Laurence Langan, an 'enforced emigrant' from Ireland, who arrived in America in 1743; John Longan, who sailed to Philadelphia in 1775; William Langen, who sailed to Pennsylvania in 1777.
