The subject of a unique trial for treason. The Logan family were wealthy landowners, who possessed the Barony of Restalrig from the 14th Century and lived in Lochend Castle. Sir Robert's father died while he was young, but he went on to inherit property in Ayrshire, Coldingham (Scottish Borders). He also inherited Fast Castle in the Scottish Borders from his mother who had taken Alexander, 5th Lord Home, as her second husband.
Logan died in 1606 and was buried in his family tomb at South Leith Parish Church. However, some two years later, suspicions were raised that Logan had been involved in the 'Gowrie Conspiracy' a plot to assassinate King James VI in 1600. The plot had been foiled and the principal conspirators, John Ruthven, the 3rd Earl of Gowrie and his brother, Alexander, Master of Ruthven, had been killed in Perth and their bodies taken to Edinburgh to be displayed.
In 1609, Logan was summoned to appear in court and his body exhumed and laid before the court. With Logan in no position to defend himself, he was found guilty on the flimsiest of evidence and his estates were forfeit.
