Edmund or Edward Sheehan born about 1805, married Mary Mahoney in Tipperary about 1832

Edmund or Edward Sheehan was born Roman Catholic in Ireland, in about 1805.
He married Mary Mahoney in Ireland about 1832.
They had Daniel Sheehan in 1832, Mary Sheehan in 1835, John Sheehan in 1839

I'm trying to determine if "Ned" Sheehan emigrated with other members of the family or if he died in Ireland. 

His wife, Mary (Mahoney) Sheehan and children John and Daniel emigrated prior to 1865.  Daniel was Baptized 18 Oct1832; Mary was Baptized 1835; John was Baptized 12 Jun 1839 all in Tipperary. On John's Baptismal record it says Walshby in the margin.  I assume there were other children but I haven't located any records.  I found a marriage record for Edmond Sheehan and Johanna Mahony in Ballyporeen Parish, Tipperary 02 Nov 1834.  I don't know if this is the correct couple, since the marriage is 2 yrs after Daniel was Baptized.
