Not personally searching for these names but thought this might help you.
I believe that www.irishgenealogy.ie
is the only on line baptism and marriage records for Kerry.
Margaret Griffin, fa: Peter Griffin mo: Sarah Farmer born
9 June 1872.
Kerry is 1 of only 4 counties that do not have membership in a History Foundation with baptism and marriages. There are
some records on:www.censusfinder.com
Griffith Valuation took place in Kerry 1852:
Peter Griffin, Parish Ballyheige, Town land Ballyheige
Union Tralee, tenant of Pierce Crosbie Esq.Reps(Parliament)
1e house and garden 1 acres 1 roods 9 perches
Peter Griffin, Parish of Ballynahaglish, Townland Tawlagh
Union Tralee, tenant of Robert Parker
Thomas Griffin same as above 10c house and garden 0.0.15
Johanna Griffin, tenant of Patrick Sullivan
1e house and garden 0.0.8
There are two Peter's as there are two houses, if one was rented out it might be 1 person.
Thomas Griffin would possibly be a brother to Peter or perhaps father whom Thomas was named after.

The telephone book for Kerry shows many Griffin's but you should be able to find the ones either close to Tralee or Listowel (Union - villages,Parishes within 12 mi. radius)
I saw 1 Griffin for sure in Listowel, only 2 Farmers listed.
I notice Curious Fox (a village contact site) has a reference for Farmers Bridge, Tralee.
Traveling Luck has a sattelite map of the area.
