Hi Robert, welcome to RootsChat.
I've had a look, but there is no listing of a marriage of James Lindsay Rae in Scotland, England, Wales or Ireland. So it looks as if he must have married somewhere in the east.
There is an obituary for James Lindsay Rae in the Straits Times of Singapore of 17 October 1940: "The death occurred yesterday at the Butterworth Hospital of Mr James Lindsay Rae, a Butterworth planter, after a brief illness. He was 56 years old and leaves two sons."
Obviously this one is too young to be the one born in 1869, but perhaps he is the son?
I also searched for James L Rae, which produced 656 results, and J L Rae, which produced 9022 results. A cursory glance suggests that most of them are spurious, but if you wish you can view them for yourself at
