Pat,
There may be a connection between the Murphys of Raheen (and other Murphys around Ballybacon) as well as Condons and Gormans and the Walshes. I have a copy of Pp 458 - 463 of The Christian Brothers' Educational Record of 1939 (Bray Printing Co. Ltd. 39 Lower Ormond Quay, Dublin) is a short account of the life of Brother John Francis Murphy (1869-1938), my GG Uncle. I have found a number of errors including his name - he was James Francis not John Francis. However, two sentences may be relevant and of interest:
"Father Cantwell encouraged the young men of his parish to marry into Catholic families in the localities where they lived, and in this way the Murphys became united to the families of the Condons, the Walshes, the O'Connor's and the Gormans..."
and
"Father Walsh, for many years Parish Priest Townsville and Father Nugent, who died in Rockhampton, were cousins."
The pdf copy is 6MB which exceeds the limit of 1MB for attachments but I can email you a copy if it is of interest.
Br. Francis in 1929 on his first visit to Ireland since leaving some 35 years before, also makes mention of several Walshes in a letter to one of his sisters in Australia. He was obviously very excited and seems to mention half the population of Ireland, though, and I'm still trying to work out who's who, who are related and who are old friends or acquaintances.
Best wishes,
Paul Ryan
