Hello Steve,
Thanks. Jane must have died. R= Reid = grandmother's name.
John's parents marriage:
Alexander BAIRD & Christina REID
27 Aug 1841 Glasgow, Lanark, Scotland
Batch: M119754
BAIRD John 28 Smyrna 1883 Sydney and family Reels 2142, 2494
BAIRD Margaret 24 Smyrna 1883 Sydney and family Reels 2142, 2494
BAIRD Christina 1 Smyrna 1883 Sydney and family Reels 2142, 2494
BAIRD Margaret inft Smyrna 1883 Sydney and family Reels 2142, 2494
A daughter born in Sydney married and died in 1965:
Death # 6100/1965 STOWE CATHERINE KEITH SHERIDAN JOHN ORR MARGARET JANE SYDNEY
So we have possible names for John's spouse KEITH and SHERIDAN.

But I'm getting nowhere. All I can say is that it's more likely to be KEITH and SHERIDAN would be Margaret's mothers name. Margaret's father is listed as Alexander and no mother listed. So possibly Alexander KEITH married a SHERIDAN.

Am I far enough out on a limb yet. :2fun: The other possibility since the informant didn't know Margaret's mothers name is that the Alexander is wrong. (Coincidence being spouse's fathers name).
Regards,
Dave
