Rick,
Please accept my apologies for taking so very long to respond to your inquiry. I am doing genealogy in spits and spurts right now as I homeschool my son.
You asked about Daniel McConnell, born about 1845 in Antrim. I can tell you I have no Daniels on my McConnell tree, but I can shed a little light on yours, I hope!
McConnell was not an uncommon name in the 19th century in Northern Ireland, of course. One of my McConnells, John McConnell (1845-1928), lived in Belfast with his family and was the managing director of Dunville's Distillery in Belfast. Dunville's Distillery was founded in 1868 by William Dunville. This was only one of several distilleries operating in Belfast during this time. Another one was the Cromac Distillery in Belfast, which was run by J & J McConnell, Ltd. They bottled "Old Irish Whiskey," or "McConnell's Whiskey." The Belfast directories show the proprietors' names as James and John McConnell, who lived on Tomb Street in Belfast from 1850 to 1892. They may have originated from the Comber area. I wonder if they might be connected to your family line. I've attached a picture I have of a McConnell Distillery promotional piece.
In my resources and reference material, I have some information on Daniel McConnell that you might be interested in. The Belfast & Province of Ulster Directory of 1870 has a Daniel McConnell living at 18 Lancaster Street in Belfast. His occupation is listed as "seaman," which fits your description. Interestingly, after that year I can't find him in the Belfast directories. Did he emigrate from Northern Ireland with his son to the northeast U.S.?
Also, FamilySearch.org has some things you might be interested in:
1) a record (Ireland Marriages, 1619-1898) showing Daniel McConnell marrying Margaret Montgomery Ross on 30 July 1864 in Belfast, Antrim, Ireland. Daniel's father is listed as James McConnell, and Margaret's father is listed as John Ross.
2) a record (Ireland Births and Baptisms, 1620-1881) showing Daniel and Margret (sic) Ross McConnell having a child named John Ross McConnell, born 16 October 1868 in Antrim, Ireland.
I hope this gives you some new threads to chase, Rick. Happy hunting!
Warmly,
Peggy
