I'm writing a historical fiction romance novel and I'm trying to gain a perspective of the travel times. The story is set in 1692, but the hero and his family arrived around 1680 from Ireland.
As a ballpark number, the Mayflower took about 2 months to do a similar kind of trip a few decades earlier. By the end of the 17th century the trip would have been a bit faster (about 6 weeks) due to a better understanding of the prevailing winds and currents in the Atlantic.
Aside: there are a few other travel related questions on this site that you might want to look into. For instance: How did passengers keep warm on sail ships? and How long would it have taken to sail from Boston to Nova Scotia in 1775?
