I am interested in John GILLIAN b 1799 at Ballentemple Ireland. He was married to a Barbara. They had a son Robert b 1821 who had changed his name to GIBSON by 1841 when he married Hannah MATTHEWS in Liverpool, England.
John 's father was James Alexander GILLIAN and his mother was called Margaret. James Alexander's father was Robert GILLILAND
John GILLILAND/GIBSON had brothers James (b 1800), Archibald (b 1813) and Robert (b 1797, d 1867)
I am interested in anything about this family and particularly why Robert changed his name to GIBSON
