Henry Keane was born 1813. He was a classical tutor at the French School Portarlington at the time of his sons birth (John James Keane) in 1845. His father was recorded as John Keane, classical tutor on Henry's marriage cert. Henry went on to become assistant master at Dr Stackpoole's school in Dunloaghaire.
I am hoping that a record of teachers/ tutors may exist so I can find a little more about John and Henry Keane. Taking a guess John's year of birth may be about 1790.
Any help gratefully received.
Cheers
Jonno
