George Gordon Carson and Elizabeth Potter

George Gordon Carson was a lawyer, and probably the son of Robert Carson, himself a Downpatrick lawyer, resident in the Downpatrick suburb of Vianstown. 

George married Elizabeth Potter, daughter of John Potter, and granddaughter of Seneca Hadzor in 1785. According to Blackwood, the couple separated around 1794, and George died on the 14th June, 1802, aged 55. 

Elizabeth  lived on, and at some point moved across the Irish Sea to Bristol, England, where she died in 1833.
