Hi Ralph. I assumed the daughters would be my best hope of continuing with this family but knowing from past experience how frustrating Irish research is I was hoping by some small miracle somebody had already 'been there, done that'.
I am thinking that perhaps marriage and death certs for the girls might be more useful. Unfortunately Tasmanian pioneer records are easily found, and are not overly abundant in their information when you do come across them.
I will try the Irish Foundations records for birth/baptisms for the girls though. Thank you :)
