I have no certificates to support my theory, but there is circumstantial evidence that the parents of the Janet Stewart whose birth was registered in Berwick Dec 1896 were John Stewart and Mary Conroy (Mar 1901 Alnwick), and that John's parents were John Stewart and Elizabeth Ann Young ( Dec 1860 S Shields).
In 1891 and 1901 John was described as a "chimney sweep". He died in 1904 (Mar 1904 Alnwick. Age 41)
Janet Y C Stewart was married on 30 October 1915. Her age is shown as 18, a spinster with no occupation given. Her father is recorded as John Stewart, deceased, a general labourer. As far as I can determine, the witnesses were a young solicitor's clerk and a railway booking clerk. The groom was a railway signalman. In subsequent census records, JYCS's place of birth was given as Berwick.
I can find no second Janet Stewart on Free BMD, or on any census return that suggests there may have been more than one individual of that name with a similar personal profile.
Is there anything further I can do to conclusively establish that both sets of records refer to the same person?
