Hello,
I notice you say you have researched a lot of Carsons. I wonder if you might have any information about Sarah Carson, daughter of Robert Carson, a farmer. She married Samuel Stewart, a farmer in Ballyvester. Sarah Carson died Jan 13, 1891 at 69 years of age & her husband, Samuel Stewart died May 14, 1907 at 77 years. They had a daughter, Margaret, who married William John Reains in India May 2, 1873. Margaret died Feb 26, 1885 at 33 years of age in Donaghadee. Samuel & Sarah also had a daughter, Isabella who was born May 19, 1868 & died Feb 4, 1882 at 13 years of age. Samuel & Sarah may have had a son, William & another daughter, Eliza, but I haven't confirmed this. Have you come across any information about this family?
