Just found your letters re Alston. He was my cousin! My father was Walter Hanrahan, who was Alston's uncle. My grandfather was John Canal Hanrahan born 26 March 1878, died 2 May 1957.
I have been doing the family tree for many many years but in recent years have slowed down! Age??
It has been difficult to find anything from Ireland, but I know gt grandfather Patrick was born in Kilshanny, County Clare about 1824.
Maybe someone knows a little more.
