Holly has Eleanor Maria Unknown born c. 1819 St. Pancras London married to a Samuel Cook born 1823 Dudley.On Ancestry a " Craiglets" has a tree with a Samuel Carlus Cook marrying a Eleanor Maria Clarke born St.Pancras London, Middlesex on 18/9/1816 and details of Ancestors and siblings of Eleanor. Tree is not very clear as shows Spouse of Samuel as Unknown but when you scroll on son Samuel Q. Cook born 1852 and back to mother it shows Eleanor. I cannot find marriage bur it is noted as 1843. Perhaps if marriage could be found it would confirm correct Eleanor and Holly can insert details from Tree.
The only one I can see with a Cook-Clarke connection. for that area. CHARLES COOK. ANN MARIA CLARKE. Marriage, 10 MAR 1812. St Sepulcre, London, London,
Thanks for the information Mumbles and Jimmy, think I left Eleanor Maria Unknown as I didn't find the Marriage. From all the evidence you have posted I think we can now be 100% that she was Eleanor Maria Clarke Married Samuel Quartas Cook 1846 Clerkenwell, many thanks from linell.
