Kate’s notes: Although this marriage notice appeared in the paper of Belfast, Northern Ireland, the marriage actually took place in Georgia. No doubt the announcement was printed in the Belfast paper for the benefit of relatives still in the home country.
    Some genealogical notes follow the transcription.

Genealogical notes:
    In the 1880 census for Effingham Co., Georgia, Thomas and Annie are recorded in a household which includes Thomas, age 36; Annie, age 33; children David, Malcomby, Monica and John; nephew Henry “Gelliland”, age 11.
    Thomas Catherwood lived in Beaufort District, South Carolina before the war, where he worked as a clerk. After serving in the CSA out of SC, he moved to Georgia where he continued as a clerk/bookkeeper. Last in the Savannah City Directory in 1895 and the tax roll as late as 1897, at least from what I could find.
    In that 1880 census which includes Henry Gilliland in their household, Henry’s father was listed as also born in Ireland. Young Henry was probably the son of Annie’s older brother, Henry. There is an adult Henry F. Gilliland in the Savannah records through the 1870’s but I do not know what happened to him.
    Regarding Annie’s father, here is his information from the 1860 Georgia Census for Chatham Co., Georgia:
John Gilliland, grocer, age 44, in Savannah, Georgia; b. County Antrim, Ireland
Henry Gilliland, merchant, age 17 b, Savannah, Georgia
Anna E. Gilliland, age 13, b. Savannah, Georgia
Arthur McCaig, age 20, b. County Antrim, Ireland
Jane, age 21, b. County Antrim, Ireland
    I do not know the connection, if any, between William J. Gilliland of Savannah and John Gilliland. An 1870 census for Chatham Co. shows William, age 26, Irish-born, living in a household that includes Mary A. Gilliland, age 37.
