I have just come across your message re Jacobus Baart. He is my great great grandfather:
Birth 20 Aug 1844 in Wijk E, Nummer 81, Vlissingen, Zeeland, Nethelands
Death 10 Feb 1873 in Vlissingen, Zeeland, Netherlands
He married Jacoba BOSTELAAR:
Birth abt 1849 in Oost-en West Souburg
Death 8 February 1922 in East and West Souburg
Their son Lein was born on 21 January 1868. He married Christina Cornelia Heijt and emigrated to South Africa in 1890 with their daughter Jacoba. They were divorced in 1896 and he remarried to Rachel Elizabeth Jacobs. Their children were Jacoba (1897), Lein Wilhelmus and twin sister Rachel Elizabeth Wilhelmina (1898), Anna Aletta (1901), Susanna Johanna Emily (1904), Marie 1906), Daniel Johannes (1908).
My grandmother was Rachel Elizabeth Wilhelmina who married Charl Petrus Francois Schutz. Their son Lein born in 1930, was my father.
I have quite a bit of information on the family. My email address is firstname.lastname@example.org
