Michael - unknown
John - 1844
James - 1845
Baptism records in Parish of their birth only commenced in 1860 so cannot provide dates for Michael and Patrick, possibly early 1840's is only a guess.
Place of birth is Ballinruan, Crusheen.
Have details of the other 2 brothers down to current day living descendants so no issues on those two. They worked on the railways before going to Kansas in late 1870's.
