HEGARTHY/HEGARTY/HEGERTY/HEGGERTY/HAGGERTY

My 2X G Grandfather Patrick Haggerty parents are George Haggerty and Mary Carney. He married Catherine Lyons Jan. 22, 1861 in Tracton Abbey, Cork, Ireland They had 2 daughters that I know of who emigrated with them in 1864 to America. Mary, my G. Grandmother who was baptized 30 Mar 1861 in Tracton Abbey,Cork , Ireland and Margaret born in 1863 in Tracton (I have not found her baptism record yet.) Wondering if there were any children prior to them leaving for America? I also am looking for Patrick's baptismal record. He was born 1840 (according to US records), possibly before.?

Any help will be greatly appreciated

. Thank you in advance
