Following on from my earlier posting (which I'm surprised no-one has commented on) re. 2 other children of Barnabas and Elizabeth Blessed. There was also another son:
George Wilkinson Blessed b.2/8/1804, bp.15/11/1804 St. Georges, Bloomsbury, son of Barnabas and Elizabeth Blessed. (His baptism has been transcribed under surname Wilkinson, rather than Blessed. He too was a Book Binder - married 1823 (and one of his children named Jabez). He died in 1846. Family transcribed under 'Blissed' in 1841.
So the 2 young orphans in 1822 actually had 2 older brothers, Book Binders like their father, living in London (George marrying 1823, and William 1825).
