On 8 March 1768 Parliament approved the cutting of the Forth and Clyde Canal through their estate, which provided some much-needed money. The canal reached the estate in 1775, but the canal company had run out of money and work stopped for eight years. The Government granted funds from forfeited Jacobite estates to start it again and the crossing of the River Kelvin became the focus for massive construction activity. Five locks, the great Kelvin Aqueduct and, between two of the locks, a dry dock boatyard were built. A village too began to grow up and the Grahams provided more land for its development; Robert Graham attached one condition that was to immortalise the heiress of Gairbraid, his wife and the last in line of centuries of Hills of Gairbraid after the death of her father Hew Hill. The then village was to be ""in all times called the town of MaryHill"".
