The famine in Ireland between the late 1840s and early 1850s is well documented in countless publications so there is no need to discuss it on this blog. Hundreds of thousands of people emigrated to the United States during those years to escape the conditions in Ireland. In fact 606,594 people from Ireland are documented as landing at New York between the years 1846-1951.
The information below is taken from ship manifest records at the US National Archives in Washington DC. In all, 17 people with the Buggy surname are listed as having arrived in New York between 1846-1851. Most are single people but there are some families in there, with two children, names unknown, born during the trip across the Atlantic ocean. A woman with the occupation of ‘wife or married’ is married to the man directly above her name. The two unknown children were born to the women above their names.
