I'll be surprised if it isn't as they had only just married.
It appears 1st and 2nd child were very close together probably 11 months? also can I ask your opinion Groom I think this is Margaret's mum's birth? see attachment I'm going by birth place Marpole
This lady was born 1911 - Margaret was born 1923 which would make her only 12 when Margaret born?

? Don't think this is the one.
In frustration I purchased some credits for SP myself - as mentioned earlier on, Margaret's mother was Jeanie McGuffie Milroy - found her in births index as born in 1900 and duly looked at certificate: she was born 23/4/1900 in Glenluce, Wigtownshire, dau. of George Milroy, ploughman and Margaret Morrow Milroy, nee Handling married 14/12/1899.
I should say 'welcome' to the vagaries of Scottish research. Whilst their certificates include far more information I should also point out that Christian names (more especially the womens) had a number of variants so on the census, for example, it can often be different to what you expect. A classic one is Jeanie - it can also be Jean, Jane, Janet! My own Scottish grandmother was born as Jeanie, known as Jean in her family, and Jane by her husband. (Another classic is Margaret who can also be Meg, Maggie).
Anyway, Jeanie McGuffie Milroy married Walter McClure 1924 (again, as already mentioned) but her death is registered as plain Jean McClure - she died 13/3/1957 Dailly, Ayr, certificate confirms names of her parents, that she was widow of Walter McClure and the informant was a John Armstrong, brother in law.
Found her on 1901 census in Inch, Wigtownshire aged 8 months as Janet McGuffie Milroy (see what I mean about names?).
If the details given for Margaret's Dutch father are untrue she must have had a very vivid imagination! Will be interesting to see if his name is included on her birth certificate - sometimes they say 'reputed father' but who knows with this one?
