Where would a European indentured servant in the American colonies live and what were the living conditions like? Would they be treated differently if they were Catholic? I'm pretty sure they weren't allowed to get married, but what if they were already married and had a family at the time they came over to the colonies? Would just the head of the household work, or would everyone have a job, including young children? Would any of this be different in the Carolinas?
If you just want to recommend a source that answers these questions (preferably a primary source), that should be fine. Thanks so much!
If you're looking for a primary source, I highly recommend William Moraley's The Infortunate, an autobiography of an indentured servant from the early 18th century - the introduction by Susan Klepp and Billy Smith and should provide you with an excellent introduction to the subject and answer most of the questions you have.
You also might want to look at Marianne Wokeck's The Trade in Strangers, which provides an in-depth analysis of migration, mostly from Ireland and Germany, in the 18th century.
Robert Galenson's "The Rise and Fall of Indentured Servitude in the Americas" is also a good article in terms of providing economic context, although it does not provide any information about the nitty-gritty of the emigrants' lives.
Edit: Also, Bernard Bailyn's magisterial Voyagers to the West is an indispensable source for understanding the nature of migration in the 18th century.
If you're interested in the Southern colonies, this article on migration to 18th-century Maryland might also be useful.
