Just concentrated on 1841 and 51.
Marriage in 1836 says nothing other than names - oh and John's job cotton carder that is it. Tried looking in counties surrounding Glasgow but found nothing with parents and child.
So it's a reasonable assumption that both were living in Barony parish when they got married, and therefore that they would go on living in Glasgow, for a time at least.
I can think of lots of avenues of enquiry, but I need more of the information you must already have to know which one(s) to pursue.
From the index at
www.scotlandspeople.gov.uk I see that Elizabeth Semple or Thomson died in Lanarkshire in 1872, aged 52. Subtracting 52 from 1872 gives 1820, so her year of birth (assuming that whoever registered the death got her age right) would have been 1819/20.
-
Have you got a copy of Elizabeth's death certificate? And if so
- Where did she die (useful for finding her in the 1871 census)
- Was she married or widowed? (useful for finding her in the census, and her husband's death certificate)
- What were the names of her parents? (potentially useful for finding out where she was born)
- Whom did James marry, and when and where? If in Scotland
-
Have you got a copy of James' marriage certificate? and if so
- What was his age on the marriage certificate?
- Where did he live at the time of his marriage?
- Were his parents deceased at the time of his marriage?
- What was his occupation?
-
Have you found James in any census? If so
- What was his age in any census?
- Where do the censuses say he was born?
Armed with all this information, you should be able to find Elizabeth in the 1871 census, which will tell you her age and where she was born.
This should help to find her in the 1861 census - I have looked at the Garrity index to the 1861 census of Glasgow, but there are too many candidates (29 Elizabeth Thomsons and 4 Elizabeth Thompsons aged 40 to 50) to know which is the right one.
- Why do you think she was born in Renfrewshire?
- Why do you think she was born about 1815?
- Why do you think her son James was born in 1836/38?
