Horatio Nelson Seymour (1801-1877) married Mary Jones Dec. 23, 1830. The only child I have ever come across was Alfred Seymour (1835-1882). He married Susanna (1828-1875) at Cahernarry, Limerick, Ireland. April 8, 1859. The Horatio Nelson Seymour Family lived in Limerick. One person who may have been a child of Horatio Nelson was married to John Laird, a Chemist in limerick. They lived at Rathbane Cottage in Limerick and we do know from a death notice that his wife's (maiden) last name was Seymour but the death notice that I came across did not mention her first name. This is the only possible child, other than Alfred, that I have been able to come up with and of course I am not sure of her either.Any help you are able to pass along would be very much appreciated.--Alfred was the father of my grandfather.
