What I have been told about at this present stage.
Joannis (John) Blackwell born 1804 in England died 1889 Southampton, married Annae Fraser of Lovatt in 1842 in Alverstoke Isle of Wight.
Children Edwardus White Blackwell born 1843 Portsea. Rodrick F Blackwell born 1847 Portsmouth. Then I have Anna Elizabetha Blackwell born in 1845 in Portsea but with a fathers name as Guliemi Blackwell (William) maybe Joannis brother not sure at all on that one . Hannah Sophia Blackwell born 1848 in Portsea. (She is my Great Gran Mother).
Hannah married Jan Van Englebert Masch born in Holland and died in Portsmouth in about 1878. Hannah then moved to New Zealand with her three daughters. Gertude Annie Marie Masch, Florence Beatrice Sophia Masch and my Gran mother Adelina Hildred Maud Masch. Would love to swap information on this family.
