Unfortunately have now found the answer for Puzzle I had on Post 33 - I say unfortunately because in fact it was David Goodsir's Grandson, from his second son Thomas :
Having checked his birth cert, which was given to Thomas & Septina , living at that time at 26, Morton Street Westoe, working as a Blacksmith, before moving to Cleveland Street
To make things worse it would appear that the newly born was named in memory of Thomas’s brother, who had died three years before he was born.
William Henry b. 8th Jan 1878 d. 4th May 1880
“ Yesterday a painful accident which terminated Fatally, occurred in Mile End Road South Shields. It appears that a child named William Henry Goodsir 2 1/2 years of age, whose parents reside in Cleveland Street, was run over by a trolley belonging to North Eastern Railway Company. The child was dreadfully injured, both his legs being broken and very much Lacerated. He was attended by Dr Bootiman and afterwards conveyed to Ingham Infirmary but he expired about an hour after being received in to that Institution.”
