Hi all,
May I please mention that we have not yet joined the dots from the Gordon BLAIR in Queensland Australia with the Gordon BLAIR who married Jane NORVAL in Scotland. May I suggest that one possible way to confirm those two Gordon BLAIR chaps are one and the same is to compare their signatures.
Gordon was the informant on the 1863 Qld birth registration for Elizabeth. A snip of that signature could be compared with the 1850 Glasgow marriage.
1850 :
https://familysearch.org/ark:/61903/1:1:XTBS-YMB 1863 : Qld BDM online index ref C540, (deduces to 3 April 1863, remembering sadly this wee baby died July 1863) Elizabeth Jane, daughter of Gordon BLAIR and Julia DROUGHTON. (While the index has BLAIR as Elizabeth's surname, it is likely that the actual registration does not give the baby a surname at all. So, similarly to GRO English/Welsh births, not until the late 1960s were babies given surnames on birth registrations in NSW, and perhaps Qld.)
