How did the Irish finance their emigration from Ireland and Scotland?

Answer 1

According to wikipedia

Backstory: Landlords were responsible for paying the rates of every tenant who paid less than £4 in yearly rent. Landlords whose land was crowded with poorer tenants were now faced with large bills. They began clearing the poor tenants from their small plots, and letting the land in larger plots for over £4 which then reduced their debts. In 1846, there had been some clearances, but the great mass of evictions came in 1847. It was only in 1849 that the police began to keep a count, and they recorded a total of almost 250,000 persons as officially evicted between 1849 and 1854.[78]

Canadian cities received large numbers of Famine Irish since Canada, as part of the British Empire, could not close its ports to Irish ships (unlike the U.S.), and they could get passage cheaply (or free in the case of tenant evictions) in returning empty lumber holds. However fearing nationalist insurgencies the British government placed harsh restrictions on Irish Immigration to Canada after 1847 resulting in larger influxes to the U.S.

According to my mother (1904-2003), whose maternal grandparents emigrated from Ireland to the US around 1835, some young Irish people came over as indentured servants.
