Some possible genealogy leads:
Richard Littlefeather from Pennsylvania, now in Australia = Richard Charles Nale as noted in corporation records
Harry Albert Smith obit, possible step father, sons listed include "Richard C. Nale, Australia"
http://www2.sharonherald.com/localnews/hed/0207/hed071102.htmlWife and possible mother of RCN is Margaret Jean McNally. Margaret Jean McNally prior was married to Richard Charles Nale Sr. They divorced in 1970.
James E McNally listed as the father of Margaret Jean McNally in a birth notice.
RCN claim "my Mother was Irish-Indian". So if I have all my ducks in a row (there always could be adoptions, wrong connections etc.), Margaret Jean McNally would be the person to focus on.
Here is her father James E McNally
