HUGHES family, Tuam Galway

[virginia3844]

My G Grandfather Walter Hughes came to Australia from Tuam Ireland sometime in the mid 19th Century.  The only record I have found for a Walter Hughes is the Griffith Valuation for CLAREGALWAY, Cahergowan or Summerfield. Of course I am not 100% sure this is him, but have found no others.
I cannot find out anything more about how he got here or who came with him.  He lived in a goldmining area in Victoria, Australia for most of his life here and married and raised a family. His wife, Julia Ronan, also from Galway lived in the towns of JERICHO, RED JACKET & DRY CREEK over a number of years and died within months of each other in 1902.  Their children were Denis, Michael, Honoria, Walter, Patrick, Wiliam, John & Maryanne.  My grandfather was Walter and I would love to find out more about the Hughes from in and around Tuam if anyone can help.
