Hi, I know it was a very long time ago you posted this query!!!
I have a Barbados death certificate. It lists - Name : Age : Marital Status : Date of death : place of death : Sex : Date of registration : Registration number (if any) : National Registration number
Unfortunately less than on a UK certificate, no mention of informant or date of birth. Trust me, the age at death is often an educated guess.
I am in Barbados so if there is any other help you need with this (I note your last entry was regarding payment), please let me know. Although, like the rest of the World, we're going nowhere at the moment!!
