Career
In 1779 he was a young officer in the Irish Volunteers and, in 1792-1793, a captain in the town"s own force, the Carrickfergus True Blues. Also in 1792, he purchased the centuries-old local historical fortification of Scoutbush, having it renovated and established as his own family residence and, in approximately 1800, initiated the construction of another prestigious local house, Glyn Park. He unsuccessfully stood for local election in 1797, but ultimately, on 27 September 1802, gained the office of burgess.
In the March 1807 by-election and the 29 April general election, he represented the interests of Downshire and was elected to Parliament.
Five months later, on 29 September, Parliament was dissolved and, in the subsequent 5 October–10 November general election, he was declared an "irregular candidate" and lost his seat. Records indicate that in addition to serving as burgess, Craig also held the local offices of deputy mayor and magistrate.
