Smith family Aberdeen

[Wellington66]

Help please.  I am trying to assist a friend who would dearly love to find some information on her father's family.  This is all she has.
Marriage 1948 Cambridge
Alexander James Smith 19 R.A.F. abode Waterbeach father Alexander Smith factory stoker
Bride (all researched)
Sometime after 1950 Alexander returned to Aberdeen and married a lady called "Betty".
My friend visited her father in Aberdeen 1972/3 She thought his date of birth was 26th April 1929 but Scotlandspeople could not find a match with the info I gave them.

I have purchased this marriage certificate. Scotlandspeople.
4th Aug. 1928 St. Nicholas Church Aberdeen.
Alexander Smith 26 Loco Stoker f. Alexander Sutherland Smith dec. Royal Navy Stoker.
Jane Lynch 28 Warehouse Assistant f. James Lynch Iron Dresser.

I think the following information relates to their son. (Who could be the person I am looking for)
Alexander James Smith marries Elizabeth Janet Riddell 1956 Leslie Aberdeen.
Electoral Reg. Aberdeen
Alexander J Smith Elizabeth J. Smith 68 Ferryhill Road Aberdeen 1957
Alexander J Smith Elizabeth J. Smith 48 Balmoral Road Aberdeen 1964-1973 (This could fit daughters visit in 1972/3).

Alexander J Smith d.1995 Insch Aged 66 mmn Lynch.
Elizabeth J. Smith d. 2016 Inverurie mmn Copland.
From Scotland & N. Ireland death index.
Mrs. Elizabeth J Betty Smith b. 8th Aug 1927 d. 1 Aug. 2016 Insch aged 89 years. (Her parents died Insch)
I don't want to waste anyone's time, I have researched all the Smith, Lynch and Riddell families I have mentioned.
What I am asking for is any ideas you might have to help me to prove this theory one way or the other.
My only thought is to purchase Smith/Riddell m.c. to see if he is a batchelor or divorced. etc.
Sorry such a drawn out tale and thankyou for reading.

My only thought is to purchase Smith/Riddell m.c. to see if he is a batchelor or divorced. etc.

That does seem to the the most obvious next step. It would also confirm the names of his parents.

Who registered the deaths of Alexander Smith and Jane Lynch or Smith and what was/were their address(es)?

Thank you for your input, much appreciated.
I have not purchased a death cert.
Index only.
Alexander Smith d. 1979 mmn Corbett aged 76 Aberdeen.
I haven't found an a death entry for Jane Smith nee Lynch.
I think I will have to order the m.c. for Smith/Riddell.

Jane Smith, other surname Lynch, died Aberdeen 1969 aged 68, perhaps? You should be able to view that one online.

Thank you Forfarian.  I have just purchased Jane's death certificate and printed it off.  Confirms all the information I had.
Can anyone tell me if a boiler attendant could also be described as a stoker?

I would have thought a boiler attendant was fairly similar to a stoker.

[Wellington66]

Sorry forgot to say.  Alexander Smith was the informant on his wife's death certificate and gave his occupation as retired boiler attendant.  Their address 181 Hardgate, Aberdeen which is also where they are listed on the Aberdeen elec. reg. for many years.

So it might be useful to find out who the informant on Alexander's death cert was. If it was, for instance, his son Alexander James Smith of 48 Balmoral Road, that would clinch it.

Aologies for delay.
Yes that does sound a good idea but.............On Jane's death certificate in the box for the informant there is no reference to their address. 
Informants's signature and qualification (signed) Alex Smith widower.
I think I will wait a few days and see if this post receives any more interest from anyone then go back to plan a and order what I think might be a second marriage for Alexander James Smith.
Thank you again for helping.

Sorry should have said only gives Jane's death place and usual address.  Nothing for the informant
