I am looking for information on the marriage of George Brown HARRIS to Lavinia Caroline ZINZAN. GeorgeBrown HARRIS was born in Dublin, Ierland in 1826. He was a merchant seaman from 1840. He married Lavinia Caroline ZINZAN in the Church of Our Saviour, Shanghai, China in 1862. Lavinia Caroline ZINZAN was born in Devon, England in 1838 to Robert Compfort ZINZAN (a surgon) and Ann Elizabeth Edwards.
Any information on these interviduals as to why of how they were in China and how to obtain a copy of their marriage certificate would be greatfully received.
