It can all depend on the line, and how well off they were to leave wills or other property arrangements, and can also depend on a lot of work trying to see how far back you can go, and what records are available. If some PR's only go back to the early 1700s then you may have reached the end unless they left a will or were mentioned in wills.
The more that becomes available online, the easier it can get.
