Throughout Scotland's past, people have been leaving, either because they wanted to seek opportunity elsewhere, or because they were forced to during one of the numerous ugly periods in the country's past, such as landlords forcing highlanders to leave their homes during the period known as the "Clearances".
Nowadays, though, many people who are descended from people who did leave are coming back so that they can explore the country's history, and find out exactly where their family fits in to it.
Whilst many will be disappointed that Scotland is not filled with people who wear kilts every hour of every day, or that the haggis isn't actually an animal that roams the Scottish highlands, they will no doubt have an enjoyable time, even when not consulting ancient birth and death records in an effort to track down the roots of their family.
The reason they'll have a great time, of course, is because of how much there is to do and see in Scotland.
Whilst staying in the country they'll be able to visit the many areas that their ancestors used to roam through, trudging up mountains and through glens, getting a real feel for where they really come from.
Exploring the land their ancestors grew up in means a lot to some people.
Even when returning to their home country, be it America, Canada, Australia, or even as close as England, they'll still have those memories to hold on to, and remind them of what it truly is to be Scottish.
Some people visiting may make surprising discoveries about their past, finding out that their ancestors were important figures in local areas, or that they were friends or acquaintances of some of the famous figures in Scottish history.
Others might be disappointed by what they find, but the trip is still one that people enjoy, even if it doesn't yield the results they were hoping for.
There are plenty of agencies in Scotland set up purely to help people discover information about their ancestors in Scotland, and many of them have websites or can arrange meetings for those who are willing to travel to Scotland.
The information is out there for those who want it, and there are plenty who do.
