John Carmichael and Ellen McManus had at least
John, born 25 March 1855
Laurence, 4 February 1857 died 1861
Helen, 31 October 1859 died 1861
Catherine, 14 February 1862
Unnamed child, 21 November 1866
all born in Glasgow
There are also at least two children to John C and Ellen Jane McManus
Mary Ann, 15 October 1868
Hugh, 14 July 1871
both born in Dalry, Ayrshire but the 1881 census proves this to be a different couple with the same names.
1861 census: Saltmarket, Glasgow
John Carmichael, 47, old clothes dealer, born Ireland
Helen, 36, born Ireland
Mary, 8; John, 6; Laurence, 4; all born Glasgow.
Mary is probably the RC child baptised in Glasgow on 1 March 1853, parents John Carmichael and Helen, no surname recorded.
Take a look at John's 1855 birth certificate, which will tell you when and where John and Ellen were married.
Ellen is described as a widow in 1881, so John sr must have died between 1866 and 1881.
However John's occupation on Catherine's marriage certificate is cabinet maker, which is rather different from old clothes dealer or hairdresser. So I am not convinced that this is the right family.
