What is reason behind bearing names with igbo suffixes and prefixes among igbo people?

It is generally common among the igbo people of Nigeria to bear surnames/family names that are prefixed or suffixed with the word “igbo”. Curious minds have often wondered the reasons behind this age-long culture among the igbo people of Nigeria with the population of 25 -30 million. It is interesting to note that there are 250 ethnic groups in Nigeria of which Hausa, Yoruba and Igbo are the major groups. Among other Nigerians it is rare or non-existent to see people bearing “Yoruba”, “Hausa” “Ijaw” “Ibibio” “Nupe” “kanuri” “Tiv” “Itsekri” “Anang” or words that are prefixed or suffixed with them.
Some school of thought have argued that the pattern of name may be due to PRIDE/PROUDNES or act of “patriotism” to Igbo nation or show of sense of belonging or to give the impression that they are “more Igbo” than other Igbo people.
From research (facebook) there are several thousands of people bearing the “Igbo”
The most popular Igbo-prefixed world is “Igbokwe”, according to research, there are about ten thousand or more people bearing the name.
All the name have meanings, some describing the nature Igbo people, culture, praises, allegiance, experiences. It is worthy to note that this pattern of naming became popular after the Igbo experience in Nigeria civil war. Names that came out after the war includes:
