Hi Claud,
Looks like it is the same Henry. The different date of birth confused me!
Henry born 1829 had 4 brothers and one sister :Hunter, James, John, Thomas and Martha. He married Margaret Griffin 7/11/1849 in St. Tomas' Church Dublin. Her father was Phillip Griffin.They had the following children that I know of: Henry, William 12/07/1854, Mary Jane 23/04/1856, Martha 4/03/1859, Margaret 10/08/1860, John 16/08/1861 and James 21/11/1866. Apart from Henry the other children were baptised in St. Mary's Church Dublin. Two of Henry's children Thomas Henry (1874) and James (1876) were baptised in St. Peter's Dublin.
I'm related to Martha 4/03/1859.
