Hi, I've tried posting this before without success so forgive me if I am repeating myself!

I'm not sure if this is helpful or accurate but I have a Hannah Attannasis Loeber born 26 Jan 1805 Wapping, London (poss died Jun 1881 Westminster London.)
Anne Elizabeth Attannasis Loeber born Dec 1841 St James, Middlesex (poss died Oct 1864 St James Westminster, London)
Sarah Loeber born Dec 1844 St James, Middlesex
These are from very brief old notes as we are from the Conrad Loeber side of the family, but I have a written scribble next to Conrads brother Michael saying he married Hannah Attannasis so Loeber may have been her married name.
I have Adam Loeber (b. abt 1771 Germany) marrying Elizabeth Harriot 1st Jan 1800 St George in the East, Tower Hamlets. As far as we can tell they had:
Conrad son b. 1800 (our ancestor)
Mary Ann dau b. 1803
Michael son b. 1804 (who I have marrying Hannah Attannasis)
Richard son b. 1807
William son b. 1808
and poss a son Christoph
I have a death for Adam Loeber 13th Oct 1848 Drury Lane, St George, Bloomsbury, Camden, Middlesex; and a burial for Elizabeth 19th Sept 1838 Wycliffe Congregational Church, Tower Hamlets.
Adam Loeber was a Sugar Baker and also owned a tobacconists in Charles Street. There is an entry for him in the London Gazette 1822 for the debtors court listing Charles Street and Keate Street, Spitalfields.
