Gore's Directory of Liverpool and Envirions 1853 - Janet Beausire, Ladies Seminary, Brighton House, Wallasey; Robert Beausire, Bookeeper at same. I was puzzled by Catherine being born in Liverpool, was she perhaps a sister in law of one of Robert's wives? I have a copy of Joseph's will and you will find a very lengthy obituary in the "Birkenhead and Cheshire Advertiser" for 12th January 1907. A Lieut Beausire, Lowenstein's Chasseurs, was wounded at St Lucia between 20/7 and 5/10 1796. If you input this regiment into "Google" you will find the very interesting paper by Curtis Jacobs entitled "The role of St Lucia during the Brigand's War 1794-1796. This gives some information about this regiment which could confirm your thoughts about the origins of Joseph from Metz.
