The single most famous Napier was possibly John Napier (the 8th Laird of Merchiston) who is known as John of Logarithms. He was born in 1550 and matriculated at St Andrews University when he was only 13 - but did not graduate! In inventing logarithms, he made a considerable impact on the study of mathematics for many centuries.
It's time to leave your exploration of Edinburgh for now and make the short journey north to St. Andrews to visit his old place of learning. As well as its academic fame, St. Andrews is also known as the home of golf, so don't forget to bring your clubs and play on historic fairways like the Old Course or King’s Course.
Alternatively, why not head west through the green landscape of Fife and on to Stirling, so closely associated with Scotland's turbulent past and the scene of one of the most important battles in the Wars of Independence.
As well as a stroll around the battlefield at Stirling Bridge, marked by the imposing National Wallace Monument, time should also be made for a visit to the impressive Stirling Castle, a royal retreat favoured by the Stuart dynasty and the childhood home of Mary, Queen of Scots. One of your ancestors, John Napier of Dumbarton, assisted Edward I in the defence of Stirling Castle in 1314.
