Abdul Rahman was the son of Andak bin Meng, a minor government official, with his first wife Hawa Binti Abdullah.

When in 1871 the childless Maharaja Abu Bakar sent a nephew, Ungku Othman, to be educated in England Andak was sent too in recognition of his potential.

In 1886 Andak received the Order of the Crown of Johor (DPMJ) (Second Class) and the honorific title of Dato’ Sri Amar DiRaja.

[1][2] He represented Johor on behalf of the sultan leading an entourage to the 1893 World's Fair in Chicago following an invitation from the United States Consul-General to Singapore Rounsevelle Wildman.

Frank Swettenham denigrated him as “a bad adviser for anyone, quite unscrupulous... and dangerous because he speaks English and has to do with Europeans all his life."
