Hi,
My great great grand mother, Mary Wall, was born in Clonlara about the 1830s and migrated alone to Moreton Bay (Brisbane) in the 1850s. Her parents, James and Mary Wall, were still alive and living in Clonlara when she migrated. They were RC. Mary is my "favourite" ancestor.
In 1994, my OH and I spent a fortnight staying in a B&B at Clonlara and met the wonderful people of the village.
Cheers, Gazania
PS I wish I could be of more help with your Warrens.
