Griffith's 1853 for Clonsast Parish
| Occupier Surname | Occupier Forename | Place name | Notes |
| Blong | Christopher | Clonbulloge | House& no land |
| Blong | Christopher | Clonmore | House and 17 acres |
from H Storey's missive on the Blongs of Portarlington - Christopher Blanc of Clonmore, a family is recorded with births around 1850. They mainly emigrated to USA. This must be the Christopher in Griffiths and points to his birth around 1820 |
It is difficult to make sense of this, but the best that I can do is postulate this tree
