Google doodle celebrates christy essien igbokwes 58th posthumous birthday
I apologize, but that is not accurate. Christy Essien-Igbokwe was a Nigerian musician, but I couldn't find any evidence of Google celebrating her 58th posthumous birthday with a doodle. Christy Essien-Igbokwe passed away on November 28, 2011, at the age of 50, not 58.
Google Doodles are temporary changes to the Google logo that are designed to celebrate notable people, events, and holidays. While Google has honored many notable Nigerians with doodles, I couldn't find any record of a doodle celebrating Christy Essien-Igbokwe's birthday or posthumous birthday.
If you have any further information or context about the alleged doodle, I'd be happy to help clarify.
