I moved your query from the STORRS Forum. STORR was not in existence at the time of my posting. Sorry for using your surname.
If I have my information correct, your mother was Hannah M born Stockton in 1917, married Robert Goldsbrough Q2 1938. Parents Alfred and Mary Elizabeth Galloway Ifthis is true, then your mother is first cousin 3 times removedto John b. 1811 and William b. 1818 who bothdied in the 1861 disaster.
The children that you mention are not William’s nor John’s. Their parents are my GGG grandparents Ralph and Eleanor Theaker.
John Robert was called Dandy because of the way he dressed. I have a copy of another private Sutcliffe photo taken when he was about 40 by my guess.
Could you verify my opening statement so I can give you the correct families?
