Hello Sea Ocean
I am new to this forum - what a wonderful website - and you have just given me my first possible family link! Very exciting!

Re: Scottish Census of 1851
Agnes Coutts, aged 6, born Arbroath, Forfarshire, at school (which puts her birth at 1845)
Living in the Parish of St. Vigeans, Arbroath, Co. Angus with her family:
William Coutts (37), Head of House, a flaxdresser (hand), born at "Morres" (probably a misspelling of Murroes, near Dundee)
Sarah Coutts (38), wife, born at Craignish, Argyll - nee Douglas according to Alexander Coutts's marriage certificate
and their 4 children:
William Coutts (16), a flaxdresser (machine), born at Greenock, Renfrewshire
Alexander Coutts (13), a flaxdresser (machine), born at Greenock - this is my g-g grandfather
Mary Coutts (3), born Arbroath
and Agnes, as above
The previous census (1841) mentions a 5th child, Ann, aged 10 months in that year. It is possible that Ann or Agnes are the same child and the real age was miscounted in 1851, but it is more likely that the child Ann died. Sarah Coutts (nee Douglas) remarried in 1855; her marriage certificate states children by former marriage: 3 living, 3 dead. So there was a 6th child as well.
So if your Agnes Coutts Livingstone is the same as mine, she was my great-great aunt.
If you have any further information about her or her parents/siblings would love to hear.
