"Francis was born 73 years ago into the family of Joseph Arinze Nwankwu and Benedict Arinze. Pa. Arinze Nwankwu who died at about the age of 87 was converted and baptised in the Catholic Church along with his wife, Benedict, now deceased, in about 1957. It was then that he adopted the baptismal name of "Joseph" with his wife, adopting "Benedict", according to Chief Christopher Arinze, 79, the cardinal's eldest brother." - http://allafrica.com/stories/200504090142.html
Could still be Francis Arinze.
