RoseSmuts on Family Tree Circles

Looking for any info about my paternal Great Grandparents, William Robert Langridge who married British German Legionaire's daughter Louisa Rohland in early Johannesburg, around 1890. William was born in London in 1864; his father was also William and his mother's name began with an E. He was rumoured to work as a butler/valet for Lord Gladstone - no confirmation found. Sent out to SA to recuperate after a fall, he worked as a billiard marker. Louisa Rohland born KWT in Eastern Cape, the youngest of 9 children of Hugo Rohland and Wilhelmina Friedericke Braun. Born around 1870. Thet had 3 children: Winifred b. 1890, William b 1892 but died 3/1893 and Charlie Arthur William Langridge b 1893. William Robert died from TB in 1894. Louisa married Thomas Henry Emery afterwards. She died around 1918. Hoping to find William and Louisa's graves.
