His father was Lukomera and his mother was Wangabira Kaddulubaale of the Civet-Cat (Ffumbe) Clan. Our Martyr was born in Bulemeezi County about 1872.

He was selected to go for the service of King Mwanga II as a page and made to serve the private chambers of the King. He was always jolly, good at sports mainly at swimming and wrestling. The boy was also playing music particularly at playing the xylophone. All that and is popular among his companions.

King Mwanga used to force him to practice blandishments, but due to the constant help of mainly Charles Lwanga, the boy always stood firm against both the blandishments and the threats of the King.

Kizito constantly besought Fr. Lourdel for baptism for fear of being put to death without being baptized. The priest always put him off because of his immature age.

When the Christian persecution broke out, the night before the arrest, Kizito was baptized by Charles Lwanga in case of emergency and given the name John Baptist.

He together with the other Christians was arrested on Wednesday morning 26^th May 1886, given a death sentence and taken to Namugongo.

On Ascension Day Thursday noon 3^rd June, 1886, Kizito was burnt to death for Christ’s sake. He is the patron of young children particularly those below the age of 15 years.
