Blueth
I think the couple in Dunoon and Kilmun in 1851 are relevant. I found this IGI entry:
John Blue Birth: 23 MAR 1827 Christening: 26 MAR 1827 Ardpatrick, Kilberry, Argyll, Scotland
Parents: Father: Dugald Blue Mother: Mary Bell
Marriages: Spouse: Margaret Ferguson Marriage: 23 NOV 1850 (this marriage shows as both a submitted entry and an actual extract from the OPRs).
It would appear that post 1855, John and Margaret moved to Glasgow where they had the following children:
1. ARCHIBALD BLUE Birth: 19 APR 1856 Clyde, Glasgow, Lanark, Scotland
2. DENNIS BLUE Birth: 20 NOV 1865 Central District, Glasgow, Lanark, Scotland
3. DENIS BLUE Birth: 26 JUL 1873 Calton, Glasgow, Lanark, Scotland
4. JANE BLUE Birth: 11 JUN 1871 High Church, Glasgow, Lanark, Scotland
5. JOHN BLUE Birth: 06 AUG 1868 Central District, Glasgow, Lanark, Scotland
6. CATHERINE BLUE Birth: 30 SEP 1860 High Church, Glasgow, Lanark, Scotland
7. MARGARET BLUE Birth: 02 NOV 1863 Central District, Glasgow, Lanark, Scotland
8. DANIEL BLUE Birth: 31 DEC 1861 High Church, Glasgow, Lanark, Scotland
9. COLIN BLUE Birth: 24 MAY 1858 Tradeston, Glasgow, Lanark, Scotland
Now, these births are all post official registration in 1855. I am thinking that if we have the right couple, Dugald would have been born in Kilmun c. 1852whilst his parents were there (we have them there in 1851).
If Dugald was the first born son, he would have been called after John's father which fits Scottish naming patterns.
What is also notable, is that a sibling search for this John shows the following names for parents Dugald Blue and Mary Bell:
1. ARCHIBALD BLUE Birth: 24 AUG 1825 Kilcalmonell And Kilberry, Argyll, Scotland
2. CHRISTIAN BLUE Birth: 30 OCT 1831 Kilcalmonell And Kilberry, Argyll, Scotland
3. MARGARET BLUE Birth: 15 SEP 1823 Kilcalmonell And Kilberry, Argyll, Scotland
4. COLIN BLUE Birth: 17 MAY 1829 Kilcalmonell And Kilberry, Argyll, Scotland
As you can see, the names are very similar to those of John and Margaret's children. I've picked out above only the actual extracted births from the OPRs. There are other entries for this couple's children, including more marriage details and deaths.
The problem at the moment is finding the family, one would think in the Glasgow area in the 1861 Census. We need to do this to find your Dugald in the household. I'm thinking their surname Blue has been mistrascribed as I'm not finding them there under that name. The family seem to have lived in Glasgow for some years given that all the post 1855 births were registered there.
