You would be well suited to READ the document before making your pronouncements.
READ it carefully. Notice when it ACTUALLY IS DATED.
Pay close attention to the last line which reads:
“Given under my Hand and Seal of Office this 17th day of February, 1964”
and Christian Name is generic for given name not last name.

From the Kenyan Embassy in Paris site.....
"The first full franchise General Elections were held in May, 1963, with KANU the winner. On 1st June 1963, Kenya attained internal self-government. On December 12th of the same year, she attained full independence. On the first anniversary of independence in 1964, Kenya became a Republic with Mzee Jomo Kenyatta as the First President."
IOW, There was no Republic of Kenya before December 12, 1964, it did not exist. As you yourself noted, the document is signed and dated ten months prior to that date.
