Hi Daisy
I see that having been born in St Pancras, George was taken as a toddler (after Edgar's death) all the way to Greenwich for baptism - and that baptised at the same time was a baby William Thomas HART.
Could there be a family connection between them?
Baptisms, St Alphege Greenwich
28 March 1852
George Harding HOWE, born 7 Aug 1850, son of Edgar (general dealer) & Sarah, of Pleasant Row, Camden Town.
William Thomas HART, born 22 Feb 1852, son of William Samuel (fisherman) and Julia Ann, of Lamb Lane.
(I see also that George himself was later a fisherman in the Greenwich area).
