1911 Irish census: Spelling variations

Cullen is much more common than any of its variant spellings or similar surnames (except for Collins of course). Here are some of the different names/spellings found in the 1911 census of Ireland.

What is interesting about this? Some of the names that appear somewhat common in the U.S are rare or absent (Cullens and Cullins for example, also Cullum/Cullom is rare--maybe it's more of an English name?) Also names mentioned in the surname histories as being variants of Cullen are absent (Culloon, Culhoon).
-------------------------------
If a number is not given, there were less than 10 people with that name in the census, usually only 1 or 2.

Tree of Y-DNA Haplogroup I2a

Besides the Cullen DNA Project, I'm also interested in my Y-chromosome haplogroup, which is a way of placing people into the grand family tree of all humanity. I drew up this tree to explain some of the new research on haplogroup I2a, and I'm placing it here so other people can easily see it. This tree is based on Ken Nordtvedt's Warped Founder tree at http://knordtvedt.home.bresnan.net/WarpedFounderTree.ppt

My cousin in Ireland and I belong to I2a1-"Sardinian" which gets its name from the Italian island of Sardinia where it is most common (this is just a convenient label--our ancestors probably never lived in Sardinia--some distant "cousins" probably were among the first settlers of Sardinia thousands of years ago).

No other Cullens are known to belong to any other group of I2a, all other Cullens tested so far are either R1b, I1, I2b1, or I2b2.
