There is also and Eric Lavender listed under ‘friends’.
Since the Copy of the Birth Certificates states “Signature of Registrar—— E.F. Lavendar” and the Signature on the bottom of the document is the ‘Deputy Registrar’ and signed by “Joshua Simon Oduya”, that only shows they are two different people representing the government Registrar’s office.
Principal office holder (Registrar) and ‘vice’ or Deputy.
I’m not sure the actual signature of the ‘Registrar’ is needed since the ‘Deputy Registrar’ is a representative of the same government agency.
The first, E.F. Lavender, is the name of the registrar in 1961 whose name appears on the referenced record in book 44B on page 5733. The second, E.H. Miller, is the registrar in 1964 at the time the certificate attesting to the content of the record was prepared. Joshua Simon Oduya is Mr. Miller's assistant who prepared and signed the document.
Oh, do you?
