HI
I'll tell you a tale my ex-next door neighbour told me years ago. the situation probably hasn't changed much since then (this was probably 1980s)
He has Sri-Lankan ancestry, I'm fairly certain not indigenous but probably British who lived there.
He was unable to find out anything long distance, so decided that one annual leave he would go there (from Australia).
He fronted up to wherever the records were kept and told them what he was looking for.
They had nothing indexed, it was all in large bound books about the size, I believe, of the big books the UK Reg.General's records are kept in. He was shown into a 'building' which was essentially concrete floors with concrete pillars supporting the next floor, etc, and no walls. [This is a fairly standard type of building for residential purposes in very hot and humid climates - to allow any wayward breezes in.] There was nothing to protect the books from rain etc. so many of them were quite mouldy.
The books were strewn all over the floor, not on shelves, and he was invited to look through them himself!
And yes he did find what he was looking for.
But he said it was a 'real education'
Sorry for the bad news
