Just reviewing this family again, and would appreciate some help sorting them out.
James Black (1797-1878) married Jane Landells (1796/7-1847) in 1817.
However I think I have two lots of children mixed up. I have
Janet or Jessie, born 1818 in Scotland died 1874 in Jesmond
Mary Weddell, born 1820/1 in Scotland died 1884 in Scotland*
William, born 1822/3 in Scotland, died 1905 in Jesmond
Elizabeth Jane, born 1825/6 in Scotland, died 1828 in Jesmond
Marion Agnes, born 1830/1 in Newcastle, died 1890 in Liverpool
Joseph Ebenezer Landale, born 1830/1 in Scotland, died 1887 in Tynemouth
John, born 1831/2 in Newcastle, died 1888 in London
Agnes, born 1833/4 in Scotland
James, born and died 1834 in Jesmond
Sarah Harrison, born 1835 in South Shields, died 1884 in London
James Gordon Mitchell, born 1838 in South Shields, died 1891 in Sunderland
Catherine, born 1840/1 in South Shields
Gavin Adamson, born 1841 South Shields, died 1869 at sea
I have baptism dates for some of them, but not for those with an inexact year of birth.
*I have seen Mary's (Scottish) death certificate which confirms the names of her parents as James B and Jane Landells.
Then I have two households in the 1841 census:
1841 Census: Barnes, Westoe, South Shields, County Durham
James Black 45 Clerk Scotland
Jane Black 45 Scotland
Jessy Black 20 Dressmaker Scotland
Mary Black 20 Scotland
William Black 18 Clerk Scotland
Merian Black 10 Not born in Durham
Agnes Black 7 Scotland
Joseph Black 10 Scotland
John Black 9 Not born in Durham
James Black 1 Durham
Sarah Black 6 Durham
Catherine Black 3 months Durham
1841 Census: Whitley, Northumberland
James Black 44 Storekeeper Scotland
John Black 9 Northumberland
Sarah Black 5 Northumberland
Gavin Black 5 months England not Northumberland
Jane Black 40 Scotland
Joseph Black 12 England not Northumberland
Mary Craig 20 Scotland
Johanna Craig 3 months Scotland
I can find only one household in 1851, which seems to include some members of both the 1841 households:
1851 Census: Barnes House, Westoe, South Shields, County Durham
James Black Head Wid 54 Commission agent and tea merchant Scotland
William Black Son Unm 28 Agent chemical manufactory Scotland
Gavin Black Son Unm 10 Scholar Durham, South Shields
Sarah Black Daughter Unm 15 Durham, South Shields
Margaret Johnson Servant Unm 21 House servant Scotland
1861 Census: West Boldon House, Boldon, West Boldon, South Shields, County Durham
James Black Head Wid 64 Merchant coals and timber Scotland
Joseph E L Black Son Unm 31 Merchant coals and timber Scotland
James Black Son Unm 23 Clerk coals and timber Durham, South Shields
Sarah H Black Daughter Unm 25 Durham, South Shields
Joseph Landell Visitor Unm 27 Commercial traveller, drapery goods Scotland
Margaret Davidson Servant Unm 20 House servant Northumberland, St Laurence
Elizabeth K Stephenson Servant Unm 15 Kitchen maid Durham, Anfield Place
Note: Joseph, son of Joseph Landalls and Margaret Telfer, was baptised in New Monkland on 17 March 1833
It would all be simpler were it not that I am fairly sure that Mary Craig is Mary Weddell Black! She married John Craig in Glasgow in 1838 and had two daughters, Jane and Joanna. John then died and Mary married John Noble in 1849 and had seven children including Mary Weddell Noble, born 1852. Jane and Joanna are listed in the 1851 census as John Noble's stepdaughters.
I have all the relevant census records for the parents and all of the children except
Marion Agnes in 1851 (she married Luke Bruce in 1850. He was a ship captain so they could have been at sea together)
Agnes after 1841
Catherine after 1841
Gavin in 1861 (he was a ship captain and may have been at sea)
So can anyone point me at any records that might help me to sort out who is who, and whether this is all one family or two families muddled up?
