Wall Family

Hello! Trying to find out about the Wall family, which appear to have a connection to this parish. 

Christopher Edward Wall, born approx 1765 (location uncertain) lived in this area from at the very least the 1830's. He was a doctor and he died on the 12/12/1865. He is buried in Glasnevin. I first found out about him via a death notice in the Bendigo Advertiser (Bendigo, Victoria, Australia), and have since also uncovered a death notice in the Cork Examiner, published on the 14/12/1865. I believe there is an obituary which was published in the Kilkenny Journal, and Leinster Commercial and Literary Advertiser, page 3 on the 16/12/1865, but I have yet to get to see the entire thing. Christopher's eldest son, born approximately 1820, had the memorable name of Martin Napoleon Wall.

I am specifically trying to find out further information about Christopher's brother and his family. The brother's name is James Wall, his wife is Eliza nee Eagan. They lived in Loughrea, Galway for some time (probably married there, and at least one child born there: James Eagan Wall) before moving to Dublin where at least one other child was born. The child born in Dublin is John Hamill Wall, who died in Bendigo on the 13th of May, 1875, aged 54 (according to his brother, who I hope would be a good informant!), which would indicate a birth in approximately 1821. I am uncertain of his religion. There may have been another brother, or a cousin, by the name of Edward Wall (I got this name from the fragment of the obituary I have been able to see so far).

It's probably a long shot, but I am hoping that the brothers were within the same parish when both lived in Dublin.

If anyone has any information, or tips on where I should look next, I'd very much appreciate it.
