My Great Grandfather was Johann Hienrich Heitmann he migrated from Germany to England in the 1860's and he was born in the year of 1842.
We are not sure on the spelling of his fathers first name because in the recording of his marriage to Eliza Rathgen of 12 Little George St, Spitalfields on the 17th May 1869 at St Mary's Church Spital Square in the County of Middlesex, his father's name was spelt Clouse Heitmann (his occupation was farmer) but we think it could be Claus but we are not sure.
We are not sure which part of Germany he came from but my mother thinks it could be Prussia.
Johann and Eliza then emigrated to New Zealand prior to 1871 as their first child Annie was born there on the 18th January 1871.
Johann died around 1881 in New Zealand, my Great Grandmother remarried soon afterwards and all papers concerning Johann were thrown away.
