I wouldn't call Nixon popular but I think there are two mentions of it in this list simply because it fits with the current surnames for boys trend and it has the -on ending and it doesn't demand to be shortened. I doubt any of the people using it have a strong association with
Richard Nixon.
Rural Australia is interesting to me because they seem to go either very traditional and old-fashioned or very trendy. I've also noticed that many dated male names or male names with feminine associations seem to be used more frequently (two of those births had fathers called
Aubrey). Some towns also seem to have their own trends that are totally not the national average each year or two. I guess the towns are so small that they all hear a name and then like it? The Arlie/Airlie thing was all going on in one town.
