I have found the Martin family name in Griffith's Valuation in 1852 in the Civil Parish of Annagh, http://www.askaboutireland.ie/griffith-valuation/ which includes Tonavane, but not in the same townland as given for the baptism of John in 1798. http://churchrecords.irishgenealogy.ie/churchrecords/details/abe2270448977
They are Patrick, Mary, Michael and James.
Above I have tracked the children of 2 of the marriages, you can use the same site to check the others, remember that they will mostly come under 'Tralee' that is the RC Parish of Tralee.
I suggest you then look for those names in the 1901 Census http://www.census.nationalarchives.ie/
Good luck Max and if you have any problems. or successes please contact me again.
Warm wishes
Martine
