Excellent. Ha! Women like to take a few years off here and there

I'll look into that..
Well, I've found a couple of things in the meantime.. One is from a member of Ancestry.co.uk, whose info is private.. he has a Catherine Milne, born 1853 in Kotri, Sindh, India.. I wrote to him, but haven't heard anything back yet. As it's private can't get any more info.
Yes, I see that Jane/Jean is no longer about in 1991.. maybe she died - 62 is a fair age at that time.
Also, got Henry's birth cert.. unfortunately the copy is so bad I can barely make out anything, except that it says illegitimate and under the mother she has crossed out several names before putting Stewart, and the father has a few things crossed out too. Mary is there also. I've sent it back to Scotland's people for a better copy/transcription.
I've still got that niggling doubt as I never found the birth certificate for Alice Milne in the UK b 1882 (the older sister of Annie Jack Milne my great-grandmother b 1885, and daughter of Catherine Milne).. though I did find a reference of an Alice M Milne born in Bangalore/Royal Engineers Regiment in 1881.. but not much more info - not even mother's name. Both are said to be born in Dundee from the census', and I have Annie's birth cert (states illegitimate/Dundee).. but wondering what on earth has happened to Alice's - unless she was born elsewhere.. mysteries.. mysteries eh?
I'll keep investigating..
Thanks for all your help Kay!
